Spark plug Bosch or Champion

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

You do know that a bosch "7" is 1 range HOTTER than stock and 2 ranges HOTTER than a NGK"7"

I bought some of those and didn't think much of them tbh. My engine prefers NGKs for some reason. Feels smoother and more eager to rev. I noticed with the F5DPORs a 'welded on' tip which looked a bit weak

STAY AWAY FROM CHAMPION SPARK PLUGS they tend to have a insulator cracking problem

After I put them in (I was one of the first in my region to carry them and use them in my own car) I found a significant loss of power. Swapped those puppies out for some Bosch Supers and I was back to where I was before I put the Plats in.
