The system is designed to fit Evolution Breather and Non Breather, and Twin Cam motors, with a version for Sportsters coming. The mounting kits, with breather passages in the arms, have adapter rings that fit: Keihin CV/Screaming Eagle 44, Quicksilver Flange and Spigot, Mikuni HS 40 & HSR 42/45, and S&S Super E and G Shorty.To the outside of the assembly mounts any one of 4 velocity stacks, and three filter assemblies for K&N elements, with more options being offered soon.

Inlet manifolds are available with flanges that mate with the shape of Quicksilver, Mikuni, and S&S, doing away with an old problem of miss-matched manifolds. They are available in oversize and undersize length to fit most stroked and bored big-inch motors. Tapered internal walls of adapter rings, manifolds and spacers mate properly with adjoining components for minimum turbulence during flow cycle.

Changing carbs? No problem, just change the adaptor kit. Street during the week, and drag-strip on the weekend? Drop the filter assembly and screw on a horn. Bored with your horn? Try a different size. Fully interchangeable components enable radical changes to your intake system, for the life of your bike. Changing your type of motors? No problem, keep your intake assembly and we can supply the required fitting hardware. Stroking or squaring your motor? No problem. We’ve got the manifolds, and spacers you’ll need.

From inlet manifolds through to filter assemblies, all components are designed and produced with Aerospace-quality engineering and materials.
