so i see alot of peopl running br8es plugs. what is the advantage of these over 7 series as well as bpr's. i see people say they run colder, but what is the advantage of that?

 

Most people i have seen that run the 8's end up switching over to the 7's

the 8 are for higher boost aps 7 are stock heat range while the the 8 is one step colder if you do some searching on hear you can get this info there is also diff.. types like the bpr8es and the bpr8ix just do some searching and find out whats best for your app

 

Ive had good results with the BPR8ES. They are colder and are more for higher boost. Just try the 2 and see which is best for you.

 

8's for me

 

7's for me...stock speaking

 

the 8es are copper and need to be replaced more often but conduct electricity better the 8ix are irredium and last longer so its your choice...

 

The max boost i run is about 1.5 kg/mc2, So should i go with the colder plug. Also how and why does the protruding make a difference. and what gap i get a differnent answer everywhere i look. isnt stock like .032?

 

What does 1.5Kg of boost equate to in PSI? The non-protruding electrode is less prone to preignite the fuel/air mixture in the combustion chamber, but, on the other hand, it tends to foul sooner in stop and go driving conditions. So,it might need to be changed a bit more frequently.

If you do a lot of city driving and run under 23 PSI, then the BR7ES might be worth a try. It is half a step colder than the stock heatrange BPR7ES.

I run a fairly stock, pump gas setup(22 PSI), but do mostly high speed highway driving. I love the BR8ES.

 

I run around 21psi. what would be the best option and what gap should they be set at.

 

I just ordered some BR8EG plugs under the advice of a local tuner. I am also fairly stock(Intake, TBE, IX Bov), but my boost is set at 22psi. I have BPR7EIX iriduims in there now, and I am experiencing some backfire at WOT. Hopefully these plugs will do the trick.

 

I perfer the 7s
