If you like Bosch plugs, use a 7 heat range. The stock 8 is fine for quick in-town trips at stock <10:1 compression. Older 8v's used 7 with the same combustion chamber and lower compression, with 0.032" gap stock. At 11:1 with a big cam and the same ignition mods, an NGK tech told me to run colder plugs (Bosch 6 equivalent, NGK 7) at 0.035" gap. He sent me a box of NGK race plugs, I gapped them, and my car ran sooooo much nicer. I was using Bosch W7DC and W7DTC (even worse) before.

Pros: car ran nicer

Cons: even worse performance

I would also recommend NGK plugs, they are made in Japan and well worth the money.

Pros: well worth money, made in Japan

I made the switch to NGK over a year ago, and haven't looked back. NGK are all made in Japan, and they're more consistent. Multi-electrode plugs hold too much heat around the center electrode, which increases the probability of detonation. Gapping the plugs is also much tougher to do. The grounds can also hold more garbage and shroud the spark.

Pros: more consistent, reliable

Cons: multi-electrode issues, difficult gapping

Vehicle: Volkswagen

That being said I ran Revo stage 1 and now APR stage 1 and in both cases I've had no issues running the NGK BKR7EIX plugs. I inspect them at a reasonable interval to make sure combustion looks good with them and it appears that they are doing just fine.

Pros: no issues, good combustion

Mileage: 13000 km

Part number: BKR7EIX

Never put those cheap ass Autolite plugs in... With that said, copper NGK plugs (brk6e) are great plugs...I was running the NGK -1 range cooler plugs (bkr7e) until the last GIAC update...and was pleasant pleased with the quality of the plugs...especially for $1.50 a piece!

Pros: great plugs, good quality

Cons: cheap ass Autolite plugs

Part number: BRK6E

Go with a normal plug (I run NGK) and stock wires. Oh, a lot of the hype about the Plat-4 is just that...hype. The spark is going to follow the path of least resistance. Meaning, its only going to go to one electrode at a time. Well, maybe if your engine fouls plugs, but otherwise, just get a set of OE Replacement NGK's.

Pros: run NGK plugs

Cons: Plat-4 is hype
