Hello there ,i have 1'3bar boost19 psi , and its time to change plugs ,is oem replacement ngk plugs good for me or try bkr7eix-11?is anyone run on eix11 s?

 

I run/recommend the ifr6d10's on the compressor motors

 

I run the NGK BKR7EIX-11 spark plugs. They work great for me. I am running 21 psi of boost.

 

boostmonkey, did you change gap size? and what size is best for high boost?

 

NGK R5671A-7
Racing spark plug
25.1 psi, third gear

 

No, the plugs are all gapped between .040 to .041. .040 is the stock specification IIRC.

 

i think 40 gap iis not good, there is bkr7eix ix sparks its same but with 031 gap(08) maby on this will better?

 

I have not had any misfire problems at .040 gap. The coils seem to be able to still handle the stock gap at 21 psi.

 

Non-resistor, nickel center electrode? I'm glad it works, but with the short life span and possible emf interference, it may not be for everybody.

 

I experimented with different gaps on the stock plugs. No positive difference detected. Currently I'm back to stock heat range with stock gap and still running like a scalded (insert fast animal). I don't think changing the heat range or gap is needed unless your boosting over 20 psi.
