08-10 Subaru WRX NGK Iridium Spark Plugs

Why should you choose NGK Iridium spark plugs for your 08-10 WRX? How about better durability, higher melting point than platinum, better anti-oxidation and anti-erosion, improved ignition, superior anti-fouling and lower required voltage when compared to OEM plugs (just to name a few). Don't cheap out when upgrading or maintaining your Subie! Go with Iridium and go with the best. NGK Iridium spark plugs are available in stock heat or one step colder variations for highly modified WRXs.

  • Notes:
  • NGK plugs are priced as a full set of 4 plugs.
  • For the best performance, one step colder plugs are only recommended for WRXs running more that 100hp over stock.
  • NGK Iridium plugs come pre-gapped from the factory and are not intended to be gapped with traditional plug gappers. Do so at your own risk.
