Reviews of NGK parts For Business
Japan
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 have tested the BCPR7EIX which did not make any difference to my car. I felt that the standard plugs worked well vs these.
Just reporting in after some usage... the NGK 4644 aka BKR7E seems to foul easier than the Autolite plugs I ran previously.
