ok i got some B9EGV because alot of people run them and i heard good things about them and im wondering at what gap should i set them? i have a street ported engine and i was running EIX's and i always had ignition breakout and i had them gapped at .048 leading because i have a MSD on the leading side and .032 on the trailing side. thanks

 

Most gap between .020" and .025". I gap at .025".

The EIX need a larger gap for a smoother idle due to being RESISTOR plugs but what you ran was too large for boost. Gap the EIX at .030" and they will be fine.

Why .048"?????

 

b9es are under $2 each and i've never heard a bad thing about them... gaped at .20 or .25

 

because i heard from people that i talked to that because i have a MSD box i have to run like .048 of gap and yes i said the same thing, why?? but i had them before to .028 and i had so much problems with them and the idle thing too. that why i change to EGV's because i wanna try them and i can boost more that .70 barwithout ignition breakout and have better start up. BTW how long EGV last?
