do you have any pics of the plugs you used?
racing spec or off the shelf?

 

Regular bpr8eix, plugs looked mint, running e85 so there gonna be pretty clean. They were a little wet with fuel when i did a wot pull and shut off right when the blowout happened. No signs of knock, det, over heating or anything. I also tryed 2 differnt sets of them.

 

So all you could get to work is the bpr8eix gapped at .019"?

 

I'm running br8es gapped at .027" on the stock 118k mile coil setup with no issues.

 

No the bpr8eix didnt work good. The p stands for protruding tip, I switched to non protruding tip.

 

^^as in the BR8ES?

 

ya, br...... is non protruding

 

BR8ES all day!

 

I'm on a ported 9 turbo running 26-27 psi on 91 octane. I've run BPR7ES, BR7ES, BPR8ES, BR8ES, and the iridium BPR7EIX, BR7EIX, BPR8EIX (when I could still find them) and now finally BR8EIX.

The BR8ES and BR8EIX behave almost the same. If you have your car fine tuned, switching from one to the other will change the way the car drives a bit.

I've finally settled on the BR8EIX because of two main things. 1) The Iridium plug I can run a slightly larger gap before spark blow out. 2) The Iridium plug returns better fuel mileage

On the copper BR8ES I run a .022 gap. While the Iridium will let me run .024

 

I like the BR7ES plugs. But, now after reading nightwlalker's reply above, I want to try the BR8EIX plug.

 

Ill go back to iridium sometime, I have $65 in plugs that I can used and have under 100miles between 2 sets of plugs.

 

I've used the bpr8es on e85 up to 35psi with no problems. Gapped at .22 iirc

 

i ment $65 in plugs I CANT used. I just bought two sets of bpr8eix plugs and I cant use them. Not new so i can return them.

 

I use both BPR8ES and BR8ES on my personal Evo 8 with no problems. 28-29psi on E85. Gapped at .022

I'd look more towards coilpacks or wires if you are having issues.

 

Its not the wires or coil packs it was the plugs. The problem is GONE with non protruding plugs nothing else changed.
