Whats up guys... just wanted to give a quick update for anybody who might find this in a archive one day. I went with the NGK plugs part # 94374; I gaped them around 0.030". I did NOT change out the COP's as none seemed to show any age (and after test driving had no issues). The hardest part of the entire process as getting the COP's out off the damn plugs. Ended up using the nail removing side of a HAMMER. There are nail puller tools/etc. but its hard to find leverage on some of the COP's. Other than that it was a super simple job. Good luck! Picture of 3 of the 6 plugs. the other 3 looked even worse. View attachment 166052
Yup, first time I did it, had a dickens of a time with the coils......
So, how does she run?
