03-05 Evolution 8 NGK Spark Plugs

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".

NGK Iridium

Iridium plugs are more durable and have a higher melting point compared to Platinum. Enjoy the benefits of reduced corrosion, improved ignition, superior anti-fouling, and a lower required voltage. These NGK plugs will get you running smoother and making 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.
