What power are you running? I would not change the ones you are using IK27 if your output is anywhere from 300 to 400bhp. They truly are the best plug on the market in my opinion.


Cheers.

Why has one died? If you have a dodgy cylinder it can foul a denso easily.

Fair enough they don't like a rich mixture.
