OK I know this has been talked about before but I've read contradictory statements. What spark plug and more importantly what gap should I be using for my stock KLZE. Right now I have them gapped to .035 and I think that might be to close.

Ok I'm bumpin my own post. I've seen NGK ZFR5F-11's and also NGK vpower BKR5E-11 Gap specs range from .035" on the corksport site to 42-43 here and there. I bought the BKR5E-11 and gapped them to .035. I just want to be sure I got my facts right. Plugs are important. Anyone?

I had a discussion with some guys about this in one of my previous posts check it out in you ned info

Searched your posts, 2 pages came up and nothing on Spark Plugs or Gap. lots on photobucket pic.

hmm I will see if I can find it

I thought this would of been a pretty straight foreward question but I guess not. I'm pretty surprised that even Google searching didn't turn up much. However if your turboing your ZE then hey, lots of posts. Can you guys/girls with ZE's tell me what your using. Thanks

Self Bump

im running with a gap of .040 and i think stock is .044

Ya 43-44 is what I read. If we had a higher voltage ignition or if you did the HEI mod you could open your gap up a bit.

Ya I saw that post, thanks. I'm gapped at .035 now IAW Corksport recommendations, I think I'll bump that up to 42-44 just to see if I feel any difference or fuel mileage change. My plugs are 5's right now and that seems to be the concenses for heat range. Cheers

my gap when i was turbo was 35 lol



the stock gap is .44

it runs best imo (i got a wideband to check air fuel ratios)

most cars are 44.

Ya right now there's something just not right. I know they run just a little rich with our ECU but something tells me I need to adjust something still. I'm going to play with my idle just a little more I think that may be out 1/4 of a turn or so. Other than that, I'll resrt my plugas ansd see if I can make my clutch slip even more..lol

Use the NGK V-Power for the 4 cylinder Probe Second gens with a gap of .44
