vs
Spark plug Autolite or OEM BMW
The truck is currently using Autolite XP5245 iridiums. Normally I would go with something from NGK but I figured if the Autolites were a decent price I would get them and they would probably last the life of the truck
Pros: decent price
Part number: XP5245
If its just painted like some cheap plugs such as some autolites then yes its needed.
Pros: needed for painted plugs
Cons: not needed if coated
So here is my experience with gaps on this engine. The wife 09 Passat was misfiring so I decide to replace the plugs. I buy Autolite double platinums which were gapped huge. Turns out the 0.032 gap was not correct after all and it should have been 0.028. Big difference, this baby flies again (GIAC tune).
Pros: baby flies again
Cons: misfiring, gapped huge
Vehicle:
Volkswagen Passat
I did track it extensively, probably 3-4,000 km of track use. The only thing it needs is brake fluid and better pads and you're good to go. My car was flawless for the entire time I had it. It threw a CEL right before I sold it that was solved with a simple spark plug change. It never overheated at the track and it was a lot of fun there and very refined and comfortable for highway travel.
Pros: flawless, refined, comfortable
Vehicle:
BMW
