I changed out the spark plugs from BKR to the ZFR long reach. Car runs awesome!! Much more responsive on the gas pedal. Engine is a bit louder, but not much of an issue.![]()
I used them and stuck with regular and no problems... Before turbo of course because now I'm running ZFR7Fs gapped at 0.030"I want to put in the long reach plugs, but I don't want to pay for mid-premium gas lol
ZFR5F-11Really? What's the full model number on them there fire plugs?
Its probably not going to add much HP but I can definitely tell at take off its a little smoother and changes gears a little stronger.Placebo. I will maintain that stance until I see dyno numbers![]()
I'm still using regular unleaded.I want to put in the long reach plugs, but I don't want to pay for mid-premium gas lol
