same everything but using a C2 Motorsport Stage 1+ tune. rippin!!
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
I was looking at pictures of the V12 engine found in the Toyota Century. Then I noticed the spark plug/coil arrangement: Interesting.
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 am using pfr7b. maybe coincidental but my 3000-6500 logs always run a few milliseconds faster. only problem with .028 are some few intermittent low rpm misfires.
Just reporting in after some usage... the NGK 4644 aka BKR7E seems to foul easier than the Autolite plugs I ran previously.
