looking for a good spark plug

[black240jl]

ok my plugs were blowing out i think and my car ran like ***, gapped they worked fine turned the boost up to 13, and it started cuttin out again, i jsut want a damn plug that will work good all the time, im not really looking to order off the net, so ima try and get em local, are the ngk iridums worth it?, and i heard u dont gap those u jsut put em in, what other plugs are good, i have the ngk R plugs right now the 6es-11 or whatever, let me know thanks

copper bcpr6es-11 plugs are all you need.check your base timing and power to coils...a stock turbo rb20 will NOT break up under 14psi.

+1

[Joe]

+1 more to copper bcpr6es.

if you do heavy track, change it to a 7. but awesome plugs.

[gawdzilla]

i had misfire issues from spark loss with ngk coppers.. bkr7e's which are i think the non JIS version of bcpr7es.

problem was fixed going to iridiums. most people don't have problems with coppers though and i would give those a shot first b/c of price

[matafied]

i myself have run just about every plug out their i think lol but the best for me by far was AC delcos from a 06 chevy malibu lol

[rb25drag]

ACDelco's FTW!!! Best plug I have found also! And i have run them all.

[black240jl]

, thanks i ran nkg 6es-11 or w/e and they sucked ***, i didnt gap em yet but still straight out the box they should be decent, hit full boost and car would fall on its face, i put the old plugs back in i gapped em to .028 and there the same plug but it doesnt say 11 on it and it works fine, cuts out every now and then..i am thinkin bout getting some irridums, anyone know the model number for the iridum plugs i would need, possibly nkg? ad on the copper 11 plugs, what should the gap be on them, i buy buy a new set and gap em and see ?

ALSO GUYS, I CHANGED THE OIL TODAY AND I PUT 5W30 IN THERE, IS THAT FINE , OR WHAT TYPE OF OIL SHOULD I USE? I AM THINKIN SENTHETIC? let me know thanks but will the 5w30 be fine? or should i change asap?

[Carl H]

the 11 in the part number means a 1.1mm gap, try gapping the bcpr6es's down to .8mm and see if that helps.

[black240jl]

oh alright

[Cjmartz2k]

Hey Carl, would that be the same number for the coppers in a RB25?

[rb25drag]

Im running Castrol synthetic 10w40!!

Does a great job.

Good luck with the plug search, There isn't alot out there and there all expensive!! Except the Acdelco's.

[BoostFab]

copper ngk 3330

[dwnshfter]

[bmart]

AC delco,s are usually just rebadged ngk's. That is why they are considered the best.

[Neejay]

copper bcpr6es-11 for rb20 AND rb25?

what?

[Carl H]

x2

what?

[dwnshfter]

copper bcpr6es-11 for rb20 AND rb25?

so just tell the guy at the parts store that i need spark plug part number bcpr6es-11 and he'll know what i need?

[bmart]

what?

Taken off another forum:Quote »Both NGK and Autolite have been secondary suppliers for GM/AC Delco for years now. [/quote]ALso, when I bought my irridium plugs for my Trailblazer, the parts guy showed me both the ac delco's and the ngk's side by side, and the stamped numbers where identical. So if you buy Ac Delco, a lot of the time you are buying rebadged NGK's.

so just tell the guy at the parts store that i need spark plug part number bcpr6es-11 and he'll know what i need?

can someone just give me a straight anwser on this please?

[rb25drag]

can someone just give me a straight anwser on this please?

Yes they will know what you are talking about.

[dwnshfter]

thank you SO very much, lol. i dont have the tools to do this here, and am going to stop on post to do it on my way back to TX tomorrow and needed to know for sure before i pull my car apart. will that part number pull up the brand as well? sorry for all the noob Q's, but i only have a few hours to get this done in tomorrow, lol

[rb25drag]

Any Parts store should be able to get that Plug or Cross reference it to a Plug Similar.

If they cant then they need to shut there doors down.

[dwnshfter]

got them, 2 bucks a plug=woohoo! i got the NGK's, just out of curiosity i asked what they went in and of course 300z pulled up as an application, could i just ask for plugs for a 300z next time or is there a reason we buy plugs by part number?

[rb25drag]

There is a reason for part #'s, Plugs have different heat ranges.

[johnny butt]

bcpr6es's will work on an rb25det though?

the 11 in the part number means a 1.1mm gap, try gapping the bcpr6es's down to .8mm and see if that helps.

So which would work better in an RB25det?

[meet07]

I dont see why you cant ask by the year, make, and model as long as it is a 300zx TT. It was turbo and pushed around 300 hp. Should not make a diffrence.

[ErnGotti]

I just got ahold of BKR9E-IX plugs for my RB20DET. I had no idea they went above heat range 7 but I think they are being discontinued. I work at Napa and there are only 36 available throughout the COUNTRY.
