Our Power Filter Kit directs cooler, fresh air directly to your supercharger delivering awesome performance and eliminating power-robbing heat intake. Unrestricted air is delivered to engine via large 4" smooth-bore ducting that is attached to supercharger with unique velocity stack and sturdy billet clamps. Cool air enters the system via a proprietary oversized, stainless-steel mesh filter element that is certified to meet U.S. Coast Guard 'SAE J1928' requirements. Requires use of RIVA Catch Can/Oil Breather Kit (part# RS19050-BCC-5). Includes water-repellent pre-filter and detailed installation instructions. Fits RXP/RXT 260, `12-19 GTR 215/230 & Wake Pro 215 models only.
