BKR7E (4644) previously known as 6097 is gapped at .035
BKR7E-E (4776) is gapped at .032
Not sure what the other differences are...
BKR8EIX (2668) is gapped at .032
IFR8H-11 (5068) is gapped at .044

Here's the response I got from NGK.
Hello,
The only difference is that the BKR7E-E has a 10k ohm internal resistor instead of the regular 5K ohm internal resistor. This is used in applications where they need large amounts of RFI and EMI suppression. It should have no negative or positive effects in your engine.
