Spark plug Bosch or NGK
I'm using the ngk 7's in my turbo 2.0...no problems..
For real, on my 2.0T I run NGK 7E's, 2 steps colder gapped .031\"
I have never had an issue with the Bosch's
They run real well on my ABA.
I personally pick the Bosch Super Plus Copper because they are cheap and last about 20-40k miles...
I'm running bosch platinum single pronges with no problem..
im running reg bosch silvers (of course the right heat range) on my supercharged setup and they run perfectttt, no misfires or anything, i love bosch plugs
That's what I am running in my wife's 94 and the idle in her car is real smooth...
I have a full obd1 wiring harness from box out 1 brand new plugs(bosh)wires(bremi) cap&rotor(bosh) bucking is not as bad
Platinum +4s are the worst plugs you can use. They have a bad habit of losing tips into the cylinders. I don't think I need to explain the results of that.
