Can anyone give me the part number for the proper HPI 55mm intake with 1.8 inch runners for a 2014 dyna switchback? Also, a recommendation on 5.3 gram injectors to go with it on a 115 - 120 hp 107?

It's on their website under throttle by wire units.

What is your setup, cams headwork, pipe? Doing my 110 build now, should be done in a week or so.
