Agree. Changing plugs are easy - well compared to changing wires anyway. Get the friend to redo your earlier work with all-same plugs.

DO NOT mix brands of plugs. I also would keep the NGK's. I've ran many different brands (and heat ranges) over the years in different vehicles and NGK has been the best plug by far.

I am currently running the NGK Iridium plugs a d have had them installed for about 5 years now with no issues. I do pull them and check them on occasion.

Yah I agree it's pretty straightforward. You did half of one brand last year and it sounds like you can either finish with the same on the other bank now, or do a do-over with a whole set of the revered ACDelco. If you thought enough to get a set of them on purpose then it's just a matter of asking whether your freind is willing to change 4 NGK to match the other bank, or do all 8 in a new brand.


You're never gonna get credit for the used 4 you did last year, but you might get a refund or at least store credit if returning all 8 of those ACD.


If the NGK are the right heat range I say pay the friend just the one beer to do the other 4 with NGK and return the ACD, but others favor American over another brand.
