Don’t just ask for a spark plug, insist on NGK.

The 98% pure copper core delivers increased heat dissipation for more reliable starts and reduced risk of overheating. While cold-rolled threads prevent cross-threading and damage to cylinder heads and a trivalent plating eliminates the need for anti-seize. Complete with a high-grade alumina silicate ceramic.

The principle of NGK's patented V-grooved spark plugs is technically simple but very effective. A V-groove is situated in the centre electrode. This forces the spark to occur at the outer edge of the centre electrode where it is easier to ignite the air-fuel mixture. In addition, the voltage required to produce a spark is reduced. These two features give the benefit of improved ignitability, especially in modern low-emission lean-burn engines, even under extreme operating conditions.
