stock B16 or GSR NGK plug here

 

i have the b16 and it wore and i got some back fire, ill try the GSR

 

12-1 cr bkr7e ngk

 

thanks....

 

i run NGK V-power R5671A-8 plugs. bam bam has them listed in the write up for building an ls/vtec as being for 12.0:1+ cr. i have p30's with a gsr head so my cr is kinda high. the plugs are good, have a slot for better spark travel (if search wasnt down id find the article by rocket).

but they get my vote...either those or the 7's.

 

Ngk Pn 5238 V power Cold 9's

 

9's?!?!?

i just had my car tuned/dyno'd and the 8's are too cold. how the hell are you running 9's?
