Not sure what spark plug to use??(351w) Any recommendations or advise??

[STANGFASTFAST]

I have a 95 gt with a 351w that is heavily modified. No power adders w/ a compression of 9:8:1. I want to put new spark plugs that will give me the most horsepower I can get out of it. Can anyone recommend the best for my set up?

Cheap ass copper core autolights. Fancy plugs are just flushing your money down the crapper

+1. I always use cheap Autolites. If you want to spend more money, then get NGKs.

im going with the Autolite platinums.....If I have time tomorrow i'm going put them in

Platinums are bad for performance. They are an absolute no no for nitrous. The platinum plugs also come at the stock gap, and you aren't supposed to regap them. Platinum is good for your longevity, but not so good for performance. I'd skip the platinums.

Yeah, don't buy Platinum unless it's a requirement for your car. And that'll only be on newer cars anyways. If I were you, I'd return the platinums, get cheapo coppers and buy yourself some jerky and a soda with the extra money

I don't think they are a requirement for any car. They just last for damn ever in a modern fuel injected car. So in order to get those 100,000 mile tune up intervals, all the newer cars come with Platinums.
