I like ngk but its really hard to find the code for NGK 1 step colder plugs.. Anyone know the plug #'s

 

ngk bkr7e

 

bcp's are better than the bkr's are.

You can get them at advanced, just tell them you want NGK part number 3330's.

 

^^^I agree with Anthony.

 

bcp7es11 for street use r5671a-9 for track

 

dont get the -11's, they come with a .044 gap

The 3330's are the same plug with a smaller gap, that means less stress on the plug when gapping.

 

why is it that ngk references v-power zfr6f-11 part 4291 for preludes.. Why don't I get those with a colder rate? I don't see the bcp #3330 on there .. how do I find those? I don't think platinum or iridium is good for turbo since both there tips are pin sized (easy to blow out). Is this correct?

 

-11 refers to the gap. what gap should I run on turbo and what # step colder?

 

The platinum on plat plugs will burn off when used on a FI motor.

Gap your plugs to .028-.030
