Hi guys,
I'm just wondering what the spark plug gap for a stock RB25DET should be? I've been getting misfiring on the last few nights and have been thinking it's the coils (they look alright but not perfect) but the spark plugs are pretty worn and are gapped at close to 1.5mm (i only got this car a week ago - so it wasn't me). from what i've been reading it should be 1.1mm. Is this right? I'm hoping a new set of plugs gapped at the proper amount should fix my problem.
edit: just found a lot of info on google that i couldn't find before (looking for 2hrs):
