Yeah can go wrong with acdelco. I run Bosch in my 93 4.3
I've run Bosch iridium's in all my vehicles (boosted and daily). No gapping needed.
Autolite is the brand I got through rock auto.
The plugs are great-- zero issues, can't tell a difference.
I've put about 100 miles on them and the car seems just as happy as ever. Went for a spirited drive today out in the hills and the car felt responsive and strong through the power range.
autolites 3923 platinumsgave me the same mpg as the expensive NGK platinum.....
My experience with auto lite has been complete trash, and their review ratings are always great. Anybody else have problems with auto lite plugs?
Yeah I own and operate an auto repair facility and refuse to use Bosch plugs because I’ve had a lot of issues with them in the past. Misfires mostly.
I've heard for many decades how bad Bosch spark plugs are and I figured the coils would be just as bad, if not worse.
Bosch spark plugs are junk.
