I put in IK20s at .4 gap on sunday... they ran great monday, tuesday morning they started misfiring under anything over 10psi... complete with flashing cel...

so I am gonna throw the stock plugs back in for a little bit (even though one looks nasty) and either regap them to .32 (even though they told me not to) or get different plugs, be them aftermarket or stock NGK...

crap

I've had mine in for several months now, and have yet to experience a misfire OR a CEL. Hmmmm.

I'd say the gap is just too much.

Seems to be hit or miss with those things....for some people, no problems. For others, misfires everywhere. Might I recommend just the regular Denso plug from your local Autozone, $1.69 each. I've not had a problem out of them. Might as well give them a shot for that price. Good luck

to be ok for now... I was only misfiring on full boost, but that is the worst time... so I regapped them (carefully... the denso web page says you can regap them, so I did) and hit the expressway for a bit... appears to be solid... so I will drive a bit and see what happens.

stupid spark plugs...

I personally enjoy using the NGK coppers :0)
