Spark plug NGK or OEM Mazda

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.

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.

I have replaced the four spark plugs with properly gapped VW (NGK) plugs and still the #2 misfires cold and randomly thereafter. The original ones looked quite normal actually - chocolaty brown. Very little wear and a .032" gap.

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.
