I don't know **** about plugs or what the numbers even stand for. All I know is that the D15b vtec uses NGK ZFR6J-11 plugs. What the hell should I switch to for boost?

description from sparkplugs.com:
14mm, 3/4" reach, 5/8" hex, gasket seat, resistor, ISO length, projected extended tip, V-power (v-grooved center electrode), .044"gap

 

BUMP?

 

SEARCH?

im using denso's, but the NGK part # is in there. alot of folks use the BKR7E

 

I searched and read those threads, but the d15b uses an oddball plug to begin with. I didn't think that that plug would be universal for almost all turbo honda's. Like I said I don't really know anything about heat ranges and numbering etc.

 

d15b vtec plugs will be the same as the d16z6.

pick up those BKR7E's and you should be golden

There is a 1 number difference and I don't know what it means. I think it's the heat range, which is why I didn't assume it would use the same turbo plugs.

 

NGK 3330's

 

Dude... the plugs are the same except for the heat range. Higher numbers mean colder plugs. Get the BKR7E's. They will fit and are decent for turbo. Get them, and test fit them. They're $2 a pop, and you can still take them back.
