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

 

try ngk R5671A-8

 

NGK v-power

1.99 a plug.

 

thats wat i have in there now the copper v powers.

 

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

 

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

 

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

How did do you determine their "the best by far" ?

Butt dyno im guessing.

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?

 

try bkr7e-11 stock number 6097 alot of people on H-T uses these plugs and i personally use them on alot of nitrous cars and high cr AM cars

 

wat r u gapping the plugs to?

nitrous cars i gap to .32 allmotor cars around .38, and <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by FST GSR 1 &raquo;</TD></TR><TR><TD CLASS="quote"> Alot of nitrous cars running what jet?</TD></TR></TABLE> anywhere froma 60 shot to a 125 so far

 

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.

 

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

 

i use 7 on mine on 35 gap

 

ngk bkre7 without the 11 on the end and i gap to 35 as builder recommends i have 11-1-115 comp dont know exaclty made 191 whp with ac and ps belts on all motor
