spark plug gap?

07 Boss · March 18th, 2009, 01:40 AM

I am changing out my stock plugs for brisk ones. What do I set the gap at? 4" CAI with L/T's going on tomorrow.

My Brisk's came gapped at .030, and that is where I left them since I am blown. I was told anything from .030 to .035 for blown applications and stock gap .045 for N/A application.

I ended up putting them in at .035. I'm N/A. do you think it will make a difference? Should I pull them back out and reset them to .045?

Come on guys, a little help here. Headers are almost in and I'm probably going to fire it up tonight. Do I need to regap the plugs from .035 to .045? Will running the smaller gap hurt me at all? Will I have any problems with combustion?

Your fine, plug gapping is a recommendation and most of the blown guys are forced to reduce the gap to avoid spark blow out under boost.

I ran mine at .040 when N/A then came down to .030 once the blower went on.

If you were making 450-500 horse N/A, I'd recommend opening that up a bit. Especially if you were cammed.

Thanks EMAY for answering me, I was beginning to think that nobody cared about me. I'm gonna leave them for now then. After I install my cams I will open them up. After installing these headers today I don't want to work on my car for a little while. I've installed 5 or 6 sets of headers in my life and this was by far the most shitty.

why did you choose the Brisk plugs??? you should be fine with the HT0's but I guess you have your reasons... as for the gap, there isn't any need to change it from stock on a n/a car...
as for the lack of answers...March Madness Baby!!!!!

Just went with the Brisk because I heard they were the best. I don't know why I don't like that strap design, but I don't. I'm gonna open the gap a little now because my car is running rich right now and don't want to foul a plug.

Dumb question coming, I could always do the research myself but what would new spark plugs get me? Do I need to get them?

I decided to change my plugs after hearing all the horror stories about about the issue that these cars have with the stock ones. My car has on 13,000 miles on it but I decided to change them out as soon as possible so that I wouldn't run into any problems.
