Spark plug and gap for Coil conversion

[Alan_11gl]

Hello Guys!

I have a audi s4 with coil pack conversion, actually have spark plug NGK bkr7e but I tried multples gaps and not found what is the best.

What is other option of spark plugs? In Mexico there is not bkr7e..

Thanks!

Not sure what you're trying to do.

The best gap is the one that allows the plug to fire for the cylinder pressure you're making.

with good coils you should be able to maintain ~0.028" gap without an issue.

So are you having misfires at WOT and blowing out spark or what? What are your mods? That might help us to help you.

I'm also have misfire/flashing cel at wot. I'm stage 3 and All my gaps are at .026, the plugs and coils look good. this suddenly popped up this past Saturday. I've also been checking for boost leaks but haven't found anything.... Any thoughts

I dont have misfires problems, but It spend more gasoline and I feel low power, buy the denso pk20TT that do you think of this spark plug?
