done a search: what's the gap for spark plugs on a 4th gen Si.. - Honda Prelude Forum

PreludeChick89 · 11-17-2002, 10:50 PM

i've heard .84.. but i'm not sure... the honda manual that came with the car lists them... that is missing and b/c the hood was replaced.... the stickers that list them are not under the hood either......

help would be appreciated!!!

They are, I always check them just in case anyways. It's not that big of a deal to spend 20 seconds each plug to make sure the gap is right.

They are pre-gapped and they should be able to tell you the gap at the auto parts store. I can check my Helms tomorrow if you still need the gap though.

i just did this about two weeks ago, they were pregapped, but just a little tight, not even a measureable distance. check 'em first.

I put them in and it runs GREAT!!!! sooooo smooth acceleration and a tad more power. My old plugs and wires were FILTHY! haha.

Its all good now. All we need to do is fix those other 3 problems. We determined the rattle to be a exhaust bracket, and the turn signal im still not sure on. the head unit should be easily fixed too. Thanks guys
