bkr6es-11 spark plugs

[Time4the16G]

Is there a difference between BPR6ES and the BKR6ES? I've read a few post on dsmtuners but none of them really have a solid answer. I order my plugs from Sparkplugs.com and they said "BKR6ES-11" were the correct spark plugs BUT i just removed my old ones which are "BPR6ES" and there is a major size difference. "BPR6ES" is 13/16 while the BKR6ES-11 are 5/8. They BOTH fit in the engine, whoever will this change my performance?? Should I send them back??

Thanks for the help

I can second this. Same plug, different size socket goes on them.

Our system uses the "6ES" plugs since we're dealing with high compressions due to turbo usage why we do the .028 gap setting.

"ES-11'S" uses a .044 gap for NT motors.

You shove in the "11" plugs in a turbo motor and good luck keeping the motor running for the higher compression will literally blow out the flame on the plug.
