Spark plug NGK or OEM BMW

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.

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.

i put another set of bkr7e's but with 0.80mm gap, the car is running a lot better now.

I installed the BKR7E gapped to .028 with no issues. My vehicles seem to favor NGK more than Denso.

Another BKR7E user. Never had any problems with them.

I too run these on my stage 2 1.8t gapped at .028 and replace them every 10K miles. So far so good.

I've run BKR7Es for years with zero issues. I've tried other plugs and I always go back.

Plus they are nice BKR7EIX's (NGK Iridium 1-Step Colder than OEM) and barely have 5000-6000 miles on them, and are gapped to the recommended 0.28 of the APR tune, so there shouldnt be issues, right? As it turns out, my engine cares, A LOT.

I'm running PFR7Bs. I get a misfire or 3 here and there, only during low load low speed acceleration. I've got R8 coils too. Not sure if the RFD makes them occur any more frequently than they otherwise would, but I'm not worried about it.

Plugs I use Platinum plugs on my tuned 1.8t .I tried using bk7re's 3 or 4 times and each time the car ran like crap. I gapped at 028,tried 030 .The engine made less power up top every time by a difference of 2/3 psi.
