MUST HAVE FOR BOOST - DENSO IK22 Spark plugs

[Si Speed 317]

I've been running the bkr9eix plugs for about 12k miles now, its my understanding that turbo 8th gens change plugs every 10k for some reason.. So I might need a new set

It's typically to prevent carbon build up

That would make sense. I'll grab a set of these soon!

What should these plugs be gapped to?

What should these plugs be gapped to?

Depends on boost and power levels, but my boosted 8th gen with ~15-16 psi of boost making ~450whp, Vit suggested a gap of like .022''. This is with different plugs, but I imagine same applies. I use the NGK iridium heat range 9 plugs.

Just gapped mine to .025, cars seems to be running good now. I had N/A plugs in there with like a .040 gap. Me and my buddy were street tuning my car because I just got done with my build. With the N/a plugs in there car would buck a bit at higher rpm. Now shes running way better with the Ik22 at .025, but still have quite bit of tuning left.

[MENTION=233]bodyman[/MENTION] Do you still have these? I'll need a set shortly. I ended up getting local bkr9eix's back then due to last minute timing.
