I have a 12 GLI with 82k and just changed my plugs for the first time. Holy cow what a difference. It had been running a little rough and even made it seem like the clutch was slipping on hard acceleration between 3 and 4. I thought it was carbon buildup, but I just had that cleaned up at 60k. The new plugs make it run like new again.

Pros: runs like new again

Cons: running a little rough

Vehicle: Volkswagen

Mileage: 131200 km

OEM plugs are good but NGK iridiums are just as good and cheaper. If your car is stock, which if memory served correctly it is, then use NGK BKR8EIX.

Pros: just as good as OEM, cheaper than OEM

Vehicle: Volkswagen Passat B6

Part number: BKR8EIX

Im stage 2+ running a .028 if i run any larger of a gap I get these weird misfires under wide open throttle. Kinda feels like the clutch slipping but its not.

Pros: good performance at .028

Cons: misfires at larger gap

I've always used NGK in my hondas and never had any problems. They're OEM equipment on most (if not all) imports so I would recommend you just stick with what works.

Pros: no problems

Vehicle: Acura TSX

As for the BKR7E's. It's proven that .028 gap is what you want with a stage 1 or 2 setup, and 0.032 for stock. No need to experiment. I've used these plugs on both factory coils and my current setup (OEM Bosch B7 2.0T coils) with no issues.

Pros: no issues, works with different coils

Part number: BKR7E

Not sure what exactly your setup is/how well you have tuned for it, but on BKR7EIX plugs @ .028 and 25psi, I was encountering some spark blowout. Basically felt like the car dropped 2 cylinders, and my exhaust had muffled misfire sounds that basically sounded like a very fast skipping CD of fart noises lol.

Pros: helped a ton

Cons: spark blowout

My car started experiencing misfires after changing the sparkplugs. Never happened before. Now it gives me a code for random misfires and #4 in particular. Today is the second tome it happened after starting the car on a cold morning. Second time 2 weeks after changing spark plugs. Just after I start, when its still cold, and never during driving or idling when warmed up. Strange. Could it be the plugs. I am using the new NGK ones. NGK Part # 1675 Laser Platinum pre gapped. Didnt have a problem with this before. I think these a are one range colder than the previous ones I had in the car. Could that be the problem?

Cons: misfires after changing, cold start misfires

Part number: 1675
