Factory LO3 Plug Gaps, and Recomendations
What is the factory specs for spark plug gap for our TBI cars? Also, having that as a baseline, does anyone prefer to gap it closer or wider? I'm using fine wire platnums. I basically just have a JET chip, intake, headers, 1.6 roller rockers, and 350 injectors. I like my timing at +4*. Thanks alot, I'm sure I could just call GM for this answer, but I figured someone here has the book in front of them. - Randy

ok, I forgot to mention I will be putting on a MSD Blaster coil and 8mm wires when I do the plugs. I also found out that the FACTORY gap is .035. I know that it has been said that it is better to run a bigger gap with the stronger coil, but what is too much for a daily driver that see's highway miles as well as waiting in lines at the track? .045 sounds safe to me, I don't think I will have any weak spots on the powerband with that, but what would you guys say about a little more? Thanks- Randy
45 is probably the most youll wanna go
youd be just as well leaving it at 35, if you can measure any difference in performance let me know 'cause Ill want your testing equipment

92RS, I like how you put all the decals under the hood on the front, I was wondering what I should do with mine, I like to keep my body clean looking

Yeah, the last thing I wanted to do was to advertise those company's names like all the honda's do, but I thought they would brighten up the engine bay a little without being obnoxious. And unlike those ricers, we get our stickers when we purchase something!

Amen 92RS. I actually just came from a 2000 Dodge Neon (which I'm pretty sure you can fit a small ci v6 into), and was going to soup it up (don't confuse that with rice it up), and even then I couldn't stand stickers on my car. Until I drive a Nascar stock car I'm not gonna do that.
To keep this tech I'm going to be gapping my new plugs when I get around to doing a tuneup. hehe
