Spark plug Bosch or OEM Volkswagen

I've been running W7DTC's for about a year now, with no problems. I haven't done any back-to-back dyno testing to see the difference between them and the usual W7DC's, so I can't comment on any power losses/gains.

I have never had an issue with the Bosch's

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 run the F6DTCs and have great results with them

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.

i've got some bosch silvers...and this happened after about 12k miles and currently (3k miles) later i'm getting similar symptoms as before.
