Spark plug NGK or BRISK

I run a cooler NGK plug in my boost increased and tuned ZR1 making 730 horsepower. They have been flawless and lead the market in the LS world also.

Today I ordered from VW TPS : - Quantum 5w 40 FS Oil & Filter - Oil Dipstick Tube - Fuel Filter - Pollen Filter - Brake Booster Pipe (Vacuum) (Pictured Below) - Interior Alarm Sensor Switch Have also ordered NGK Iridium plugs from Awesome GTI

As for the plugs, I bought [these NGK plugs]

NGK spark plugs are fine.

Been running NGKs in Sportsters forever with no issues. Good plug.

i run BKR7E at stock gap on stage 2 30psi. no problems at all even in 100 degree heat.

I would strongly recommend using NGK PZFR5J-11 spark plugs. These NGK Laser Platinum plugs are the best option for your 2.5l. Not only are they pre-gapped and ready for installation, but they'll perform great and provide dependable service for several years.

I've only ever used NGK plugs in my girlfriends old 2.5 and my current 2.5 (both cars have a total of 150k miles between them) and have never had a problem. They have also never needed to be gapped. Just take em out of the box and install them.

I'm getting some knocks in all cylinders in the first revision, more than I did with the Cobb OTS map and stock spark plugs. Hopefully it gets sorted out in the next couple of revisions and if not, I'll have to check the spark plug gaps or maybe re-run with the Cobb OTS and see if the knocks are due to the tune or spark plugs.

Overall, the power delivery is great.

Just reporting in after some usage... the NGK 4644 aka BKR7E seems to foul easier than the Autolite plugs I ran previously.
