NGK BKR6E vs. BKR6ES Performance differences?
 

BKR6E - copper core 'V Power' (OOOO!!!) needs to be regapped. I've been using these for a couple years, changed every 5000 miles. Great plugs.

BKR6ES - copper core standard plug, pregapped to .032.

Any real differences? I bought both and I think I'm going to use the BKR6ES this go round.

You may have some problems with it gapped to .032. I was having cold start problems and misfires.

Yep.. 0.028 gap FTW. (assuming 1.8T)
