Picked up some NGK BKR7 Iridium plugs from Paul over at dezod. Paul told me to gap them between .026-.036. I asked Joe_Dezod what to gap them at too and told him what paul told me. Joe said not to gap them so close because the stock timing system dosen't like it when you re-gap plugs. Says he runs OEM gap. What is the OEM gap?? And also, for the boosted folks, what gap are you guys running?


Thanx!

 

OEM is .044 I personally run iridium gapped at .040 which has turned out perfect so .044 stock would be fine as well. Also I highly advise running iridium fine wire plugs in any boosted engine weather it be Denso or NGK. Both are stellar performers and have very long lifespans. I had egt issues for some reason running a gap under .030... Changed it back to .040 and it went away so I think I was not igniting all the fuel and dumping it out the exhaust... smelled like it also.

 

NGK Iridium BKR7's up to par?

 

i ordered the ones recommended on garage1217's site (NGK). i had them in since i had the turbo and they seem to be working fine for me. o ya, order from garage1217, good service, lol.

 

BKR7s are Iridium NGKs!

 

Here comes the whole NGK/Denso war, let's not start this.

 

bkr7eix is iridium, thought he was refering to a bkr7e which is a common nickle tip v-power turd plug

 

Not at all, both are stellar plugs and no one would be able to tell the difference between them. Denso runs slightly lower resistance but also cost allot more. Cannot go wrong with either.

 

Yo paul, what were thes bkr7's pre-gapped at again?? Joe's helped me decide to run a gap of .040

 

Ok please do not waste your money on these expensive plugs. Boost loves copper plugs. BKR7E's are possibly best plug that I have put on my srt and at $2 a plug that is a hell of a deal. I gap them a .23. If you are running too large of a gap you will get blow out. Try the coppers and you will love them.

 

That is why you run fine wire plugs such as iridium or gold paladium over crap nickle tipped plugs. You can run a wider gap which results in a better fuel ignition without the risk of spark blow out at higher boost levels. The so called copper plugs are not even copper *LOL* just a generic name given for them back int he hot rod days because back then NGK bragged about having a copper core and that was high tech for the day. The so called copper is just a junk 1.1mm nickle tip lawnlower plug. The fact is, all plugs run copper cores and there is a reason the mast majority of ALL manufacturers specifically use a longer life fine wire iridium now when they could just stick in a junk bkr7e

Also consider this. Average NGK iridium ix runs around $6-$7 a plug and lasts 60-80K miles under most boosted applications. Your crap nickletips under boost last about 10K miles tops before the edges of the nickle start to round. You do the math which comes out much cheaper price wise over 60K miles / labor wise, and they perform better! Very much a no brainer.

 

well you got to take into consideration that most people are only pushing like 8-12 psi. And another reason I like the "coppers" is because it forces you to look at the plugs more often and you can see if you are running too lean/rich off off the plug.

 

thats what gauges are for lol

 

tell that to my friend who's wideband was 2 points off.... gauges are not always dead on.

 

Your plugs are not going to tell you within two points of a wideband anyways. Just lets ya know ..
1 if you are way to lean
2 if things are close
3 way to rich
4 Your motor is screwed

 

Tell your friend to buy a better wideband.

 

/\/\ word

 

your friend probably had his bung welded into his exhaust plumbing either too close upstream or too far down stream. 26 inches is ideal.
