From an aesthetic perspective, the Rushmore Air Cleaner Cover is a big hit with a lot of folks.
The look, with the scoop up front, is something that appeals to many, much more than the football style, or even other aftermarket style A/C covers.
However, the backplate, the filter and the breather system on the Rushmore Air Cleaner really have the intake choked down.
DK Custom Products has designed a HiFlow Air Cleaner System specifically for use with the Rushmore Air Cleaner Cover.
The back is opened up, the filter element is K&N, it comes with your choice of External Breather Systems, in short, The Outlaw HiFlow 606 Air Cleaner will breathe more air than the Twin Cam can eat, AND the Rushmore Cover fits perfectly on it.
