Spark Plug Gap?

[Cammaxon]

What are people running for a gap on their spark plugs?
NGK R plugs, magnacore 8.5 wires, E85 and 26psi

OEM says 32, my car would studder and missfire
Was tuned on 25 gap, it had a few misfires at first then LOTS
brought it down to 20 (my lowest gap) and had random misfires...

If your still getting misfires at .020 then id check your wires, they could be arcing out.

he has low compression in a cylinder...

[blackrosenova400]

Wait is it misfiring under boost or all the time?

[Cammaxon]

Randomly, but only under boost.

[blackrosenova400]

Id check for bad wires.

Yeah .020" is a very small gap. Most I would ever go down to is .024".

[Cammaxon]

should i bring it back up from 20 to 24? ill check all the wires over tomorrow.

[4g63tcrazy]

I would. Ideally you want to make the gap as big as possible without blowing out the spark. I would be testing other things to figure out why your misfiring. Time to swap out ignition parts.

where would you start?
