NGK Iridium and Copper V-Power Spark Plugs for Lancer Evolution 8
NGK Spark Plugs for Lancer Evolution 8
NGK 03-06 Evo 8 Spark Plugs NGK IRIDIUM: More Durability and a Higher Melting Point compared to Platinum, better center electrode anti-oxidation and anti-erosion, improved ignition, superior anti-fouling, lower required voltage, new metal shell plating process for better anti-corrosion. One Step Colder plugs are recommended for cars with heavy modifications. These NGK plugs will get you smoother running and more power through increased efficiency and increased heat resistance.

NOTE:Iridium plugs are able to use larger gap setting with less voltage. Some customers choose to re-gap these plugs to correct misfiring or tune for optimal spark -- do so at your own risk -- a slide-type plug gapper can damage the fragile iridium tip.
NGK V-POWER COPPER: V-Power spark plugs are a patented design by NGK to improve ignitability and reduce quenching. Ignitability is improved by the V-groove cut in the center electrode parallel to the ground electrode, this directs the spark to the edge of the center electrode thus exposing it to more of the air/fuel mixture. These are an OEM type plug with a hot spark, the downside is that they have a shorter service life. We recommend changing plugs on your Evo with every oil change. Gap should be around .032".
