Hi
Ive read a bit about spark plugs and was thinking of getting the platinum NGK ones (BKR6EP-8/2215) as they have good reviews and are long life. I was just wondering if i should go one colder and get the BKR7EP ones? I have a 3" exhaust and am running at 15psi. I don't often boost it so mostly stay under 12psi, but with the increase in boost would it be safer to have colder spark plugs for when i do thrash it or is it not a good idea or not necessary?? Thanks for the help in advance This post has been edited by mikee: Aug 26, 2009 - 5:08 AM |

Thanks for the help in advance look at your old spark plugs. if they look clean you can afford to go colder.

Good thing I'm stock 5sfe, but I'll keep this in mind for when/if I ever do any compression work. -TC Hot spark plugs are important to keep the tips clean as they burn off anything that sticks to the tip. If you constantly foul spark plugs, then you might want to change to a hotter spark plug. But if you take your spark plugs out and they look clean and your not getting any knock/pinging then stay with what you have. |

Everything is burning perfectly, the only plugs I've ever fouled were in pocket bikes and go-peds due to carb tuning. :-D -TC This post has been edited by razor7: Aug 26, 2009 - 4:23 PM -------------------- Live your life for yourself.
