92 grand prix spark plugs

02-01-2010, 12:27 PM

sorry to bring up this question again, but previous posts don't really cover it. Maybe it's due to the fact that most questions pertain to the newer dohc motors..
Anyway, I'm wondering which plug to run on the gf's car? I always run ac-delco, but the original R42LTSM is unavailable through autozone. Is there a reason for this? -Didn't check other stores yet. And I've seen the recommendations for the rapidfire 8 plugs, but autozone lists the 12s for this application. What would be the correct route?

according to rockauto, the rapidfire 12s are correct.

1995 Monte Carlo LS 3100, 4T60E...for now, future plans include driving it until the wheels fall off!
