That's about the dumbest thing I've heard in a while. The br8es is a great plug for your evo. You may want to close the gap a little.

Sorry, couldn't resist. I'm back to the factory NGK's because of that bad experience. But I do wonder what makes up the difference in price. Iridium seems more expensive by default. But what do you get for the extra $18?

I've been running this same plug in 2 strokes since 1980 just 1 step hotter. They just plain work and don't foul if you use the right heat range.

Copper plugs are run way better in my EVO than the stock IR. Just have to change the out sooner.

Are you using the stock airbox?

+ 1 on the possible spark blowout

I've encountered the same issue on rare occason... Pretty much as full boost hits, it sputters and looses power...

I could also hear it, sounded electrical, like a series of small pops. Luckily I was logging at the time... It registered as knock, but it was false...

I was told not to start with the gap of the plug... That would just be a band-aid... If it continues to happen look into the coil or wires (and new plugs)

Is your tune completely finished? If the car is still running rich, that might be contributing.

yeah my tune is finished. I have since went back to BPR7ES and my car runs like crap now! It does pull harder but it sputters really bad, its not smooth running like it was with the BR8ES. I bought a set of BR7ES to see if its going to make a difference.

WOW! I just barely got done putting BR7ES the stutter is barely noticeable! I Guess, I'm going to stick with these for now. Man I hate 91 octane with a passion. I Think the BR8ES was too much for my mods! Thanks guys for the advice!

I spoke to frenchy about this...

his tune was done pre walbro 255 install so he's going to be retuned for that...I'm sure it's incredibly rich and I also suggested to go ahead and close the gap on the plugs to .023 instead of the stock .026 on those plugs.

After trying numerous Irdium plugs, i'm back to BPR8ES

More mod's than this guy, so he's probably better with a 7.

Post oe spec plugs*

sounds like spark blow out---* also, you are not supposed to gap the plugs on the evo's you can damage the plug , and run into weird driveability problems etc.
