I'm thinking of changing my spark plugs soon. I got the following mods on my TII. 2" DP, 3" Exhaust, NO CATS, 3" Intake, 680cc Secondaries, Walbro Fuel Pump, RB FCD & boosting between 10-15psi. What brand spark plugs should I get and what temperature degrees for Trailing and Leading?

 

I always run NGK's, im not sure what the temp rating is on them but I have never had a prolbem with them.

 

Only get NGK. Go to www.racingbeat.com and check for their recommendations on spark plug temp for your mods/driving style. I would e-mail them or give them a call, they will probably have the best info for you.

 

try the ngk b9ev

 

they're right I work at an auto shop that works only on japanese cars and we only use NGK

 

You don't have that extensive of mods to run 9s all around. Run 2 b7ev in the leadings and 2 b9evs in the trailing.

 

I run NGK 10's on the street and 11's or 11.5 on the track
