RIVA Performance Power Filter is installed. Power Filter replaces restrictive factory air filter, resulting in improved throttle response and top-speed.

RIVA Free Flow Exhaust Kit is installed. Kit replaces restrictive sound suppression system located between waterbox and hull exit reducing backpressure and engine operating temperatures.

Worx Intake Grate is installed, resulting in increased top speed in choppy water conditions due to improved pump efficiency. Prop spin and cavitation found with the stock grate is greatly reduced along with the modified FX's tendency to drop on its nose when the throttle is let off at high speeds.

Solas DynaFly Impeller is installed. After extensive impeller testing we found the Solas DynaFly to be the best all around impeller. Billet impeller nose cone included.

NOTE: RIVA Performance Kits intended for competition use only.
