Spark plug NGK or Champion
Ngk Platinum all day
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
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.
Just swapped out some pretty old looking OEM bosch plugs that were gapped at .045 for some reason. Put in PFR6Q at .032\". Didnt notice much of a change.
Just reporting in after some usage... the NGK 4644 aka BKR7E seems to foul easier than the Autolite plugs I ran previously.
