yes that is the correct plug, I used this plug on e85 with a whipple 2.3 on 20 psi and worked perfect.

I thought so, it was weird it says for a jaguar is the only application on summits site. Did you use the out of the box gap??

E85 generally like a bit hotter plug. I just swapped BR7EFs for TR6s gapped .028 at 20psi

out of the box gap is perfect.
