For the archives' sake, that's .028 inches, or 0.7 to 0.8 millimeters.

BPR6Es is recommended for stock applications, BPR7ES is recommended for track cars or heavily modified cars with over 75 hp over stock or significantly higher boost levels, and 0.26 gap is what most run with anything over 16 psi...
