current mods are
-dc sport header
-greddy ti-c axle back
-fujitsui cold air intake

and will be ordering weapon r intake manifold, cat delete, etc, possibly the t1r crank pulley.
so my question is with this setup should i order the ngk ik22 that kraftwerks sells or the ik20 which seems to be the stock heat range

 

Guess ill order the 22s and hope for the best

 

denso Ik22 will work just fine.

 

cool thank you

 

At what stage was your car when you installed the IK22s and what did you notice about them if anything ?
