NGK WIDE RANGE SPARK PLUGSWIDE HEAT RANGEA wide range spark plug is more flexible and performs equallywell in a hot or cold engine under stop and go city driving orfast motorway cruising. 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. With theexception of a couple of older applications all the spark plugsin this catalogue employ copper core technology.FIRING END APPEARANCE2

SPARK PLUG INSTALLATION TIPS Refer to current NGK catalogue for correct spark plug selection1 Check condition and cleanliness of threads in cylinder head Ensure plug is gapped according to vehicle manufacturers specification (fig 1) Multi ground electrode and precious metal plugs should not be regapped - visualinspection only Install new spark plug by hand until it seats - (fig 2) a length of rubber tubingpushed over the insulator can be a useful aid for plug installation where access isdifficult2 Tighten to specified torque setting as shown in the chart below (fig 3) If a torque wrench is unavailable then refer to vehicle/engine manufacturersinstallation instructions or the tightening angle advice which is displayed on currentNGK packaging (excluding specialist race plugs). 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 Ø18mm14mmCast iron head35-45Nm(3.5-4.5kgm)(25.3-32.5lbs ft)Aluminium head35-40Nm(3.5-4.0kgm)(25.3-28.9lbs ft)12mmTAPER 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 packagingSPARK PLUG GAP SETTINGSImportant: Spark plug gap settings are given in millimetres.Practical equivalents are shown ins.016 .020 .024 .028 .032 .035 .039 .043 .051 .055 .059 .063 .071 .0793
