hey guys i am looking to run one step colder plug in a ngk anyone know what it is, i am told part number 3764 is it, but just want to be sure cause i checked one place and it said would not fit crossfire. is a BRKEI5-11 the stock plug??

 

NGK BKR7EIX-11 spark plugs are one step colder.

thanks steve, so what is a BKR6EIX-11 plug, i don't know why this turned red but whatever, tvt told me to run that plug and that it was stated as stock but it truly one step closer, just trying to check up on it.

 

I would guess two steps colder. LET sold me the 7's stating they were one step colder.

Here is a list of "stock" plugs that work in the srt6, just increase the number on the heat range to order a colder plug

this should help you see how to pick a hotter or colder plug:



the higher the number the colder the plug, if your stock plug was pfr6a-11a and you wanted 2 steps colder then you would get a pfr8a-11a

 

-5 is stock on the N/A, -6 is one step colder and stock on the SRT, -7 is one step colder for the SRT and could be used for heavily modded and/or high Nitrous N/A

 

I checked the TVT site and it looks like the -5 is the "recommended" performace plug fot the SRT....yes? (I am guessing for no serious mods)

 

A lot of the C32 owners prefer using that plug for a better idle and driving response. I have no personal experience with that plug in that motor.

 

i have the 6's for my wet 75 shot, needswings intake, exhaust, and soon to have underdrive pulleys
