Denso Iridium IK 24's
 

Are these the correct heat range to run for 500whp or 20-22lbs on c16. Are these plugs worth it or should I go back to a reg NGK plug. If so what would be the part number. thanks in advance. rob

DO NOT run iridium plugs in a high hp turbo car! the iridium part will come off in the combustion chamber

So what should I run then? Im going back to the dyno for some race gas tunning and want to have the right plugs in the motor. rob

regular NGK's are best.

I am a fan of the ngk 3330's.

So, did you end up using the Denso's? Did they work out for you? Im considering these plugs as well.

Really don't use Iridium denso plugs, huh we have them in the Pro FWD Hatchback(650hp), Pro FWD Coupe(850-900hp) and the Pro RWD Coupe(1400+hp). They all work great with these plugs never had a problem.

Yeah I know. We have them (same plug actually, the IK24) in our 800+ supra. Bullish recommended these plugs at the time when the car was being dyno'd. I love how bad info gets spread around https://honda-tech.com/forums/images...es/emdgust.gif
