SPARK PLUG SELECTION FOR CLASSIC ENGINESA number of factors have to be considered when selecting suitability of a spark plug for classic and vintage engines, whichcan differ from the originally recommended item.The following points need to be considered before looking at available spark plugs: Intended use (Competition / Hard use / General Road / Commuting / Low speed or Vintage road runs / Museum) Condition of engine Fuelling / Timing set up Modifications (including upgrades to ignition system)All the above points can have a significant effect, and even result in engine damage if the incorrect spark plug is used.LONG TERM STORAGEClassic and vintage engines are, by their very nature, less likely to be used as everyday vehicles. If fuel is left un-used for aprolonged period, then the fuel can become 'stale' over time. When the engine is attempted to be started, the stale fuel canwet foul any spark plugs and fail to start. A sensible precaution to prevent this issue is to drain any fuel from the vehiclebefore storage. Modern fuels can be susceptible to degrading more quickly, becoming harder to ignite after perhaps just 3months. There are proprietary fuel stabiliser additives on the market, designed to prevent this from occurring, but NGKcannot comment on their effectiveness as we have no direct experience in the use of these products.RESISTOR SPARK PLUGSMany older ignition systems are based on lower voltage magneto set-ups. NGK resistor plugs use a high quality ceramicmaterial for the resistor construction, which provides a very stable resistance level, typically 5k Ohms. Even a magnetoignition system can produce tens of thousands of volts, which is more than capable of running a resistor plug. The actuallevel of resistance at the electrode gap under combustion chamber pressures is far greater than any resistor installed in aspark plug. Resistor plugs can and are used by many owners with this system without any issues, providing the ignitionsystem is in good condition. Some owners successfully use the modern NGK Iridium 'IX' range of spark plugs inconjunction with magneto ignition systems. One advantage of the 'IX' range is the use of a very fine-wire centre electrode(0.6 mm diameter), which requires less voltage to create a spark, beneficial when using a low powered ignition system.HEAT RANGE AND INTENDED USEThe heat range of a plug is a measure of it's ability to disperse the heat of combustion. Put simply, a spark plug does notproduce any heat, but must manage the heat it is subjected to from the combustion process to maintain its optimumoperating temperature (between 450-870 C). Please note this temperature refers to spark plug firing end (nose)temperature and is not related in any way to cooling system or oil temperature. If the firing end of a spark plug exceeds870 C then the ceramic can ignite any fuel on contact, leading to pre-ignition and subsequent engine damage. If the firingend of a plug falls below 500 C (the minimum self-cleaning temperature) then carbon can accumulate on the insulator,eventually leading to a misfire as the current leaks away to ground. This is why selection of spark plug heat range is criticalfor the engine the plug is intended for. NGK spark plugs use a low number (e.g. 2,4.) for a 'hot' (soft) spark plug designed to retain relatively low combustion chamber temperatures in the firing end of the plug to prevent fouling. A 'hot'plug is usually found in horticultural equipment. A 'cold' (hard) NGK spark plug will have a high number (e.g. 8,9,10.) designed to disperse the high combustion chamber temperatures quickly to prevent the firing end from overheating.'Colder' type plugs are usually found in high performance equipment (sports bikes/race cars).The actual use the engine is put to can also have an affect on combustion chamber temperature. Many vintage or classicmachines are subjected to occasional starting whilst in storage or they are left to warm up gradually by the owner beforeuse. Whilst this is mechanically sympathetic for the engine components, it can be detrimental to the spark plug. This isbecause the idle mixture can be very rich, and/or the combustion chamber temperatures lower than when in normal roaduse. This can quickly lead to fouling of the plug firing end, again eventually resulting in a misfire.Another cause of fouling of the plugs can result from how the engine is used. If we take, for example, a classic motorcyclewhich originally has a 'cold' NGK B8ES spark plug recommended for the machine when it was new. This 'cold' spark plugmay have been perfectly acceptable when the bike was used every day, under 'spirited' use by the proud owner enjoyingthe full performance of their new machine. If this same machine, 30-40 years later but still in exemplary mechanicalcondition and set-up is only used on very low speed club runs, then the original plug heat range may be unsuitable as itcannot reach its operating temperature. In this instance, if the present owner decides they are not going to use themachine any harder, then a 'hotter' B7ES may be a more appropriate spark plug option, providing they understand therisks of pre-ignition in using a 'hotter' heat range.2
SPARK PLUG SELECTION FOR CLASSIC ENGINESThe reverse of this example can also be relevant. If we take, for example, a road production vehicle which is only used bythe current owner as a track or competition machine, then the original recommended road plug could overheat if the engineis in constant full-load/high speed use. In this case, if the standard recommended plug is a B8ES, then a colder 'B9ES' maybe a more suitable spark plug, to cope with continued high speed use and associated higher combustion chambertemperatures.One point to note is that 2-Stroke engines are far less forgiving on plug heat range compared to 4-Stroke engines. If theheat range of the plug selected for a 2-Stroke is too 'hot' (soft), then the dangers of pre-ignition can quickly lead to the'dreaded' melted piston conclusion.FOULINGFouling of a spark plug to the point of misfire occurs when the surface of the ceramic insulator surrounding the centreelectrode is coated in contaminants, which allows the spark current to leak away to ground. Any particles adhering to theinsulator surface can provide a conductive path for electricity. It should be noted that these particles do not come from thespark plug, and as such fouling is always a result of particles within the combustion chamber, rather than a fault of theplug. There are many causes that can create fouling of a spark plug, incorrect fuel mixture, excess oil entering thecombustion chamber, stale fuel or incorrect heat range selected, to name a few. In all cases, replacing the plugs cantemporarily cure the misfire or starting problem, but if the root cause is not identified then the fouling problem will eventuallyre-occur.A tactic sometimes employed to overcome oil fouling of spark plugs in an engine that suffers from excess oil in thecombustion chamber is to attempt using a 'hotter' (softer) grade heat range. This is in effect treating the symptom ratherthan curing the cause, one of the only examples where a 'hotter' plug may be selected, as long as the risks of detonationare understood first.MODIFICATIONSModifications carried out to an engine to increase its horsepower will increase the combustion chamber temperatures. Anypublished NGK catalogues are for un-modified production engines only. When an engine is designed by a vehiclemanufacturer, hundreds of hours of testing and design are dedicated to ensure that each engine component will operate tosatisfaction across a variety of engine and environmental conditions. Any engine modification in effect alters the enginecharacteristics and as such, it is the end users responsibility to ensure that every engine component that may be affected,is considered and re-specified if necessary. This is especially relevant to spark plug design and heat range. It is notpossible for NGK to provide a recommendation for a modified engine. For NGK to make a recommendation, the spark plugneeds to be tested and certified for that engine. Suggestions can be made regarding plug types to test, but the list formodifications and variations is endless and as such making a recommendation is not possible.SUMMARYIn essence a spark plug is a simple device for creating a spark, although as can be seen above, it is a very complexsubject that can involve many different designs, materials and heat ranges. The spark plug can be affected by manyexternal factors, which can alter its performance.3

Spark plug design musttake into consideration many features of an engine including physicaldimensions, combustion chamber shape, cooling abilities, fuel andignition systems. Spark plugs play a vital role in producing themaximum power from an engine whilst keeping fuel consumption andemissions to a minimum. Choosing the correct spark plug type willhelp a vehicle manufacturer meet legislated emission targets andassists the motorist in getting the best from their engine.Increases in the size and the requirement to improve the cooling ofthe inlet and exhaust valves have meant that the space available forthe spark plug is severely restricted on some cylinder heads. Achange in spark plug design, possibly the adoption of a taper seat andextended reach (threaded portion) or even the use of a smallerdiameter is often the answer. Some engines require the use of twospark plugs per cylinder and again due to space restrictions thesemight be of different sizes.Changes in fuelling systems and the fuel itself have meant some specialfeatures being adopted at the ‘firing end’ of the spark plug. Extraprojected types push the spark position into the heart of the combustionchamber to promote better combustion of the fuel/air mixture, which isweaker than ever in an effort to improve economy. Modern enginemanufacturers often require increased spark gaps to allow a longer sparkduration, which again aids more efficient combustion.Wide gapTwin groundBPR5ES-13BKR6EKThree groundFour groundBCP6ETBKR6EQUPExtra projectedand shieldedPrecious metalZFR6E-11IZFR6BTo combat the ‘cold fouling’ effect that can occur in some engines using unleaded fuels specially arrangedground electrodes are sometimes used. These can force the spark to discharge across the insulator and thusburn away any built up carbon that could cause poor starting or misfires. It is not uncommon to find two, threeor four ground electrode arrangements in new vehicles. The use of precious metals on the tips of the sparkplug electrodes is not uncommon especially on higher performance engines. Whilst these spark plugs do haveincreased service life they are often specified because of their superior ignition qualities.Our engineering departments work very closely with the engine and vehicle manufacturers to produce the idealspark plug type for each application. Any change in production is expensive for a manufacturer and thereforenew spark plug types are only produced where necessary. NGK employ the very latest production technologyto ensure that every aspect is catered for – performance, economy and value.HEAT RANGE AND HEAT DISSIPATIONSpark plugs do not produce heat in the combustion chamber. One of the functions of the spark plug is to dissipate someof the heat produced during combustion. This is mostly transferred into the cylinder head. The 'Heat Range' indicates themeasure of the spark plug's ability to dothis. A 'hot' spark plug is designed tomaintain a sufficiently high temperature atthe insulator nose to burn off carbon andoil deposits. A 'cold' spark plug is designedto allow a faster transfer of heat to thecylinder head thus preventing overheatingand premature failure.The heat range selection is obviously acomplex task with many factors to takeinto account. NGK engineers thereforemake specific recommendations for eachengine and the use to which it is put.244

Engines that tend to run hot need coldtype plugs. Those that run cold demand a hotter type. Thespecific plug for any engine is determined by the plug's heatrange. That is the minimum and maximum temperaturesbetween which the plug will offer optimum performance.The heat range of NGK Spark Plugs is wider than ordinaryplugs therefore they are suitable for both high speed and lowspeed driving. Compared with conventional plugs of the samepre-ignition rating they have more resistance to fouling.Compared to ordinary plugs with equal anti-fouling resistance,NGK Spark Plugs have a higher pre-ignition rating.NGK'S HEART OF COPPERCopper wire used in place of the iron core in conventionalplugs is the secret of NGK's Wide Heat Range. Copper'ssuperior heat conductivity dissipates heat quicker. It cools theelectrode tip and insulator tip which prevents hot spots thatcould cause pre-ignition. Increased heat resistance does notaffect fouling resistance, which is primarily determined by theinsulator nose length. The longer the nose, the moresusceptible it is to heat and the more free from fouling. Byraising the pre-ignition rating with the high conduction copperand leaving the insulator nose long, NGK produces the WideRange Plug. One that meets the broad thermal requirements ofengines under high and low RPM conditions. All the sparkplugs in the Automotive Catalogue have a copper core.FIRING END APPEARANCE535

Note that this angle advice candiffer between part numbers due to individual spark plug design (e.g. seating type,thread diameter and gasket material) It is important not to over or under tighten spark plugs during installation. Overtightening can lead to distortion of the spark plug. Under-tightening can causeoverheating due to poor heat dissipation. In extreme cases incorrect tightening cancause spark plug breakage and/or engine damage NGK does not recommend the application of lubricant to spark plug threads as theresultant reduction of frictional forces at the thread faces will render the torquecharts inaccurate and over tightening could occur If a gasket type spark plug is re-installed, it should only require a further 1/12 of aturn after it has been seated Always carefully use the correct tools for removal/installation to prevent damage tothe spark plug or engine Inspect spark plug cover and renew if necessary3FOR FLAT SEAT TYPE (WITH GASKET)Thread Ø18mmCast iron head35-45Nm(3.5-4.5kgm)(25.3-32.5lbs ft)Aluminium head35-40Nm(3.5-4.0kgm)(25.3-28.9lbs ft)14mm12mmTAPER SEAT 2.5kgm)(18.0-25.3lbs ft) (10.8-18.0lbs ft)10-15Nm(1.0-1.5kgm)(7.2-10.8lbs ft)-20-30Nm(2.0-3.0kgm)(14.5-21.6lbs ft)15-25Nm(1.5-2.5kgm)(10.8-18.0lbs 6lbs ft) (10.8-14.5lbs ft)10-12Nm(1.0-1.2kgm)(7.2-8.7lbs ft)8-10Nm(0.8-1.0kgm)(5.8-7.2lbs ft)20-30Nm(2.0-3.0kgm)(14.5-21.6lbs ft)10-20Nm(1.0-2.0kgm)(7.2-14.5lbs ft)Important: Some spark plugs differ in gasket design or material, refer totightening advice on specific spark plug packaging646
