Spark plug Autolite or OEM Volkswagen
Reviews
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
Can't beat the 2.5 for hassle free reliability. Economy sucks, though. I have had my 130k mile 2.5 Rabbit since new and I have never averaged more than 25-26mpg in mixed driving, but on the other hand I haven't done much more than oil changes and spark plugs on it.
Pros: hassle free reliability
Cons: economy sucks

I changed the spark plugs to Autolite Double Plat plugs from Autozone. The smoke cleared up and it is MUCH easier to keep cranked in the cold (30's F) in the morning. It still has a very light stumble every few cycles and a louder engine idle than I'd like, but runs good and seems to be much better.
Pros: smoke cleared, easier cold crank, runs good
Cons: light stumble, louder idle
Vehicle:
Volkswagen Passat B6
Look out for tensioner. Somewhat large maintenance at 40k intervals. (DSG fluid and filter, haldex fluid). Oil changes every 5-10k. Spark plugs every 40k a good ideal imo as well.
Pros: Spark plugs good ideal
Cons: large maintenance

Cons: busted while removing
