Denso ITV24 Spark Plugs Two Steps Colder

These two step colder plugs are recommend for those running high boost levels.

These are NOT pre-gapped by us as you will need to run a gap tight enough to eliminate ignition misfires with your fuel and boost levels. We recommend 0.026" as a starting point.

(NOTE:Dropping plugs into the hole can result in a closed gap, please be careful to install them with a proper spark plug socket that holds the plug) Tighten to 15 lb-ft or 1/16 turn after seating.
