Why should you choose NGK Iridium spark plugs for your 2.5RS? 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 plugs are priced as a full set of 4 plugs.
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.
