00b20vtecoupe

Hi, im running a fully built b20 vtec setup with 12.5 cr and im wondering what the best spark plug set up is. When it was built i belive my tuner used standard ngk coppers. Idk if it was b/c the motor runs hotter and copper is better or what but i tried running iridiums 1 time and it ran like ****. Just wondering what people are running in similiar setups and whats recommended... thanks

What is the life on these plugs (i.e. mileage)?

tensecpass

boush plus 2 is the best by far. they have plus 4 too but i run plus 2s

98vtec

you mean the ones with extra ground straps to block the spark from getting to the fuel?

Have you ever heard of flame kernel?

currently running v powers and i believe gapping is about .038 due to recomendation on here. as i hear rec. for high cr would be about .038 for a smaller gap. stock motor reccomends .052. is .038 a good gap for high cr b20 vtec?

There really is no such thing as a "shot" size, thats why I asked what jet. Since your nitrous jet should never change in tuning.

most 60 hp kicks are around 038 n20 and 022 fuel dont hold me to it but i think thats right

Are these single nozzle systems?

Anything over "100" should be more then 1 step colder.

1SiC 3DR

yea single fogger nozzles i usually go 7 heat range because most people eventually want more cant blame em really
