what NGK plug (copper) for 250-300whp RB20det??

[blues14]

So I was just gonna clean up my coilpacks today since the shop that did my swap changed the plugs and I thought awww, what the hell, I will just check my plugs to see what they look like. So i pulled one and found out the peices of sh@% that did my swap pul elcheapo 3924 AUTOLITES in my car after I specifically asked for NGK's. so now I am changing my plugs and need to know which copperr ngks to run. would the BCPR7es-11 be the right plug?? what gap?.08? what are you guys running?

BKR6E ?! gapped around .23

i havent had any luck with NGK in my nissan! spent 90$ on their best plug and fouled thim out in an hour! their only good for hondas, or maybe im just running to rich (stock 25 with 275rwhp 10psi) but if i was you i would go with a denso plug

[gawdzilla]

BKR7E or 6E depending on how hot/cold you want to go. higher the number the colder for NGK.

if you get the ungapped ones you will find the gap is already pretty close to .8mm. double check them and put them in.

bcpr6es-11 gapped to .8mm should do the trick for you.

+1, perfect plug for you. i ran the 7es' in my 25 it was right around 250whp. never had a problem.

RB's love copper plugs.

dropped them in today... bcpr6es-11's.... two of the Autolite plugs were not even finger tight!!! SCARY STUFF, GLAD I CHECKED THEM! Thanks again guys.

[Carl H]

lol, lack of power much?

[blues14]

not really, the car seems to overall run smoother since replacing the plugs, I just couldnt believe a "tuner shop" would even consider putting autolite plugs in an rb. and then to not even torque them

[Joe]

actually a lot of the aussie guys swear by autolites.

its just a spark plug man, dont take it so seriously. (but id be mad about how not-tight they were)
