just wanna make sure that this ngk is stock heatrange...i google already some say its 1 step...sone dont. i know thw 8 is 1 step..just wanna make sure thanks guys...im thinkin of changing my spark plugs..my car is all stock other than upper icp and intake

 

That or BR7EIX would be correct irridium plug for stock to mildly modified evos.

You'll be golden with that plug

 

so i should get the br7eix

 

You'll find a good amount of debate between bpr vs br and it sounds like it mostly comes down to preference. I run the BPR7EIX on my 05 MR w/ stock turbo + boltons and they work great.

 

+1

 

ok..ill c then...thanks for the help

 

Ive been running the BR7eix iridium plugs and they work great. Im running a mild setup, 273 awhp @ 21 psi.

 

I have been running BR7ES in mine. I think copper plugs are fine. Heck, I run Autolites from Wal-Mart in my 9's second Mustang

 

cooper brp7es is the way to go, b/c it cost less and perform just as good.

I switched back and forth between heat range 7 and 8 and it makes no difference!

Remember cooper has better conductivity than iridium and platinum, just look at the periodic table of elements.

 

The bpr7eix are iridium stock heat range, the bpr8eix are the one step colder plug. There both a good plug, I personally ran the copper bpr8es for a while, there cheap but worked ok still got an intermitten misfire, now im running the Denso iw24, which are also one step colder iridium gapped at .024 and car drives great with it. So just make sure stock heat range or one step colder and stay iridium dont go cheap with a copper plug, they do work but theyll foul out quicker.

 

^ I'll stay with the coppers thanks. I change em out every 5k. Never had a spark issue up to 30lbs on a 35r

It's not going cheap it's making sense

 

the br is 1/2 a heat range colder than the bpr with the same number

 

well to each there own gsrboi, i never said the copper plugs were cheap, even though they are cost wise, but the idea of changing your plugs everytime your changing your oil, seems a bit too much, i personally like mine, between the denso iw24 plus my sparktech non cdi cop, no misfires at all, car runs like champ.

 

what gap are people running?
