i run autolite 63 (gap to 24 thousandths) on my stage 4 for 500 miles with nitrous, they look perfect. 99 cents each. to each his own.
Pros: look perfect, work great
Mileage: 800 km
Part number: 63
Plugs have been on for almost 4 days. No problems! Idle and runs smoother! HP feels the same!
Pros: no problems, smoother idle, smoother run
Vehicle:
Volkswagen
The part number I have for the Bosch is 4418. There web sire below only goes up to 2000 EV so I don't know if these are the same as the 2001 + EV. I really love these plugs and ran them in my prior Audi A6. Long lasting, great even spark, no gaping. Bosch claims (see web site) increase power. Maybe?
Pros: long lasting, great even spark
Vehicle:
Audi A6
Part number: 4418
I bought a set of NGK BKR6E plugs and gapped them to .032\". It seems like they are just fine for the 1.0 bar chip I have. I don't feel any change in acceleration so, the previous Bosch F7LTCR plugs must have been ok. Eitherway, I'd rather have the NGK's due to their price and easier gapping method.
Pros: just fine for chip, easier gapping
Part number: BKR6E
I use NGK BKR6E plugs I switched out my factory Platinum for these beacuse alot of people on Audiworld did. They all said that it had a smoother idle with the coppers. They were right.
Pros: smoother idle
Part number: BKR6E
It has been satisfactorily argued that the inexpensive Autolites work as well as the expensive Iridiums, with the understanding that the Autolites must be changed more often.
Pros: work as well
Cons: changed more often
I've run the platinum +4s in my GTI and I haven't had any problems but I haven't found them to feel any different than any other plug.
Pros: no problems
Cons: no noticeable difference
Vehicle:
Volkswagen
And I tried both the Bosch and the NGK back to back, and the NGK ran far better than the Bosch. The Bosch were terrible in my case.
Pros: NGK ran far better
Cons: Bosch were terrible
I just put Bosch Copper plugs in my 2.0 L Passat and it's running like crap. I think I forgot to gap a couple of the plugs... Would that explain the rough running engine?
Cons: running like crap, rough running engine
Vehicle:
Volkswagen Passat
