I plan on running nitrous soon and was wondering what kind of plugs to run, I did a search and found somone saying NGK BKR7E plugs. Are these universal plugs? Will they work in a H23? why are these so cheep (found them for $2.50 ea) are they better then the over priced platnum plugs?

 

BKR7E is a B-series plug as far as I've seen. If you want colder plugs for a H-series, look for ZFR7F-11. Those are copper and run around $2.00-2.50

 

Actully it was laughinxxx who said it in another nitrous post I just dont want to order a set only to find out they are the wrong ones

 

I also need the colder NGK's for my H23. Don't get a platinum tipped one, b/c when you spray it will just burn off the platinum that you paid extra for. Is there a better place to buy them from other than the local NAPA?

 

I run BCPR7ES-11's, part # 1095 at Napa

I run the same. Good plug.

 

and this is a colder plug (BCPR7ES-11) which would be suitable for a nitrous application?

 

Yes, one step colder than stock

Does anyone know what to GAP the BKR7E at? Do they even need to be gapped? =D

That would depend on what you are using them for.

I didn't GAP mine at all. I used it as it came out of the box, and it works fine for All-Motor H22A

 

I'm using ZFR7F-11 plugs. I've also used BKR7E's... I prefer the ZFR's because of the projected tip

 

what would happen if your allmotor and use one step hotter to help with burn off the carbon buildup.

also whats the difference with ZFR7F-11 and BCPR7ES-11

Depends on what you think All Motor is....

ZFR7's have a projected tip

 

Just rev the car alot. No carbon.

 

The bkr7e's are not just a B-series spark plug. They work great for all the other honda motors as well. The 7 series are also 2 stages colder then stock, since stocks are 5 series. Usually for all motor apps you want a stage 6.

The projected tips are not the best to use for a FI application since the tip will sit a bit further down inside of the combustion chamber. The tip will be exposed to greater heats and can lead to pre-ignition and/or detonation.

The BCP7ES are the plugs to use. Get plug number '3330', they are the exact same as the 1095 but come with a gap of .032 instead of .044. That means less stress the tip receive when re-gapping them for your application.

The BCP7's are better then the BKR7E's because of what I mentioned earlier. The BCP's have a shorter insulator and tip then the BKR7s do. The further it sits in the combustion chamber the plug tip will be exposed to higher temps which can lead to pre-ign or deton as mentioned earlier.

p.s. I believe XES runs the ZRF's with over 500whp but when compared to the bcp's you can see the bcp's are theoretically 'safer.'

Cliff notes: 3330's work great

 

bkr7e, i think that's the same plugs i used in my turbo accord before.

they work fine, not too cold to get foul so fast.

depends how you define all motor, if you put a hotter plugs in and your compression is ultra high, bang, two flame front

copper works just fine for honda, v power copper for me

 

What would be a good plug to use for all motor. 6 series plug with nice gap and who sells them..?

Thanks in advance..

 

ok ive tried a few differnt plugs. isnt stock a 6 heat range not 5? h22 anyway.

i used the zfr7's and it worked great. the bcpr have a flat electrode while the zfr's have v-grove. i have the bkr's in there now, and maybe thats my problem...thought it was the igniter but im going to try that.
