I've run the BKRs in my GSR. They perform identically to the ZFR6F-11 copper plugs recommended by Honda for the B18B1 in warmer climates in my experience. I've since switched to ZFR7F-11 plugs, a bit cooler, since increasing the car's muscle.

 

im in nj so it will be getting cold soon , what are the colder ver of these plugs i have and second, does it make a diff on a i/h/e car ??

 

The ZFR6F is probably the most appropriate copper plug for your application. The ZFR5F is the plug recommended for the B18b in normal climates.
