Review on RK 3943 Intake Davidson Non CARB Compliant by Jake Larson

I like that I can put more air in the engine without affecting the factory look BUT I wish it could take in a little more air. Special air intake will definitely give you better performance, but I like the factory look of my sports car. It was a difficult compromise, but I'm not entirely disappointed. Installation was pretty easy and everything needed (no tools) was in the box including screw lock. There were a few parts of the setup that were awkward, but if you can't handle them then you really shouldn't be working on your own bike.
