spark plugs
I was wondering what kind of plugs are recommended for an 88 IROC 5.7 L engine. When I put my engine together I used AC R45 TS plugs,gapped at .035.I have seen 43 TS or something like that on my friends 91 firebird. What are the right ones? It is just going to be a daily driver so I just want to keep everything as factory as possible.
