Ford Racing M-12405-35 T 10 s/p ?

[joe raptor]

Hey brothers , what's the gap on this s/p ? I'm running E-30 w/ MSD cop's . Are they real goo or better than the Brisk Racing ones ? I'm changing the Brisk for this new ones, cause at idle my car surge a lot to the point that the engine stops when I'm on a traffic light and is getting frustrating !!!!! Thanks

I'd try .028" to .030". Silver is a better conductor than platinum or Palladium by far. You might even be able to get away with wider than that. The close Gap is used to overcome The increased resistance created by hi-boost and the high resistance of the Platinum Family metals.

Your issue is likely not the Brisk plugs. I've been using this plug at a gap of .027 just fine. That plug you want to change to is also a good plug, however and would be fine to use as well. They are simply re-designated SP542s.

If you are having a spark issue, I'd be more inclined to blame the MSD coils...they've been known to fail more readily than OEM.

OEM coils are just fine and I would recommend sticking with them....

The MSD coils were working fine until I changed to the Brisk s/ps !! Can any s/ps gurus really tell me finally which s/p is good for my car ?! Getting tired to waist money buying s/ps !!!!!!!

N14 + Brisk plugs= misfire? - North American Motoring

Drivetrain (Cooper S) - N14 + Brisk plugs= misfire? - Has anyone with an N14 R56S successfully ran Brisk silver plugs without a CEL? I have been running Brisk MR12S plugs in my 2010 R56S, and I get misfire codes and CELs every damn Thursday. Any insight would be appreciated.

This is why I suggested running a wider Gap.

I run the M-12405's at .026 gap.
