Which spark plugs with supercharger?

Chris_H · 01-26-2002, 05:24 PM

Ok, now that I have had the car running good for the past week, I have been wanting to change out the spark plugs for maintenance anyway. Now that I have my Novi 1000, what would be a good plug to use? I am currently running the motorsport plugs, at the reccomended gap and heat range. Are those sufficient enough, or should I go with something else? Any help you guys can give me is appreciated.

I'm using Autolite #24 with my blower @ 7 & 10 psi.

Like Pac said, the Autolite 24's are your best choice. What do you have them gapped at Chris? I would recommend no more than .035.

You should run a colder plug. I have Autolite 3923 with less gap.

Ok, so what is the real difference between the Autolite 24's and the Autolite 3923? Also, which gap should I run. Like I said, I am still running stock reccomended plugs with the stock gap. I am hoping to change these out in the next week or so. I appreciate the help so far.

My suggestion is to consider IRIDIUM plugs. Reliable sources say iridiums produce significant gains in supercharged applications, even with a spark box like an MSD.

I'm getting a set this week. They're coming from X-M-P.com .

The 23's are a colder plug.

Ok, I guess I will go with the Autolite 24's with about a .035 gap then? Can I get these at Autozone or Checkers by chance?

If you have an O'reilys, I'm pretty sure that they stock them.
