I am going to be installing 272 cams next week, and plan on changing out the plugs while I am at it. I was wondering if I should change the heat range and what brands everyone recommends. My mods are(will be) as follows: Helix 272 cams, walbro, Apexi Intake, DC Sports Downpipe and Cat delete, Helix Exhaust, APS BOV, and custom flash by Jestr. Thanks for your input guys!!! This place ROCKS!

 

You should be good with one heat range colder.

 

NGK BPR8ES

You need to update your waiting to be installed list and who will be installing and how sexy he is

 

goe with the ngk bpr8es works great

 

Im actually getting my cams install this weekend to and we have or will have similar mods and I was told to go with the BR8EIX from NGK

 

really?? I have just about every bolt on mod too with FP Green turbo comin and it was recommended to use BPR7ES, as I have been from the beginning.. I'm not questioning why, but should I upgrade as well to the BPR8's?? thanks for any advice.. Mike

 

I would think the only advantages would be that they will last longer and help make your wallet lighter. I figure I'd rather change $8 in plugs every other oil change than change $100 in plugs once a year or so.

 

No, there is no benefit on going to a colder range of plugs. You are still on your stock turbo, so no need. It's just a waste of money. Spend your $$$ on something else.

 

What is the reason for going to a "colder" plug in the first place?

 

 

Not really. It has to do with boost and with the stock boost and stock turbo, you don't have to go to a colder plug. But yes, it does do what rcheung said.

 

ok that kind of makes sense. I understand premature detination, but the spark is happening the same time with either plug so how does a colder plug prevent it prematurly detinating? Sounds like maybe its simmilar to turning timing back in that there is more delay in the spark with a colder plug? or more delay for the colder plug's spark to create detination?

Excuse my ignorance here.

 

the colder plug removes more heat from the cylinder....thus taking away another component that can cause detonating..i have the br8es..it helps when running high boost...they just foul easier then the "BPR" 8/7 heat ranges and above

 

OK that seems logical.

 

so is the stock plug sparks recommended for a "stage 1 upgrade" with no meth or alky and running 23-24 psi on a stock turbo?
