quick spark plug question
i know there are a lot of old plug threads but what is the general consensus between the delco 41-110 irridiums and the NGK TR5IX irridium plug?
need to do plugs in my 2002 z and was curious what the go-to plug is for a stock engine
i also noticed there is a tr55ix which appears to be the larger gapped version of the tr5. seems like a .040 gap would be more detonation resistant than .050

that's what i'm thinking. the delcos are $1 a plug cheaper and it's oem i suppose. i've always been a big ngk fan but like you say, it probably doesn't matter one iota
quick question on the GM red wires, the $60 ones from gene culley. do those fit the factory heat shields? seems like the wire everyone is using
