RXT IS 255 STAGE 1 KIT 2009

RIVA MaptunerX Yamaha Bundle is utilized to reflash original ECU. MaptunerX provides ability to quickly and easily load performance tunes directly into your stock ECU eliminating downtime that results from shipping for programming. Performance Tunes are calibrated to provide optimum fuel delivery, ignition timing and rev limit to compliment RIVA Racing Performance Kits. OEM dash display, engine diagnostics & engine safety functions are retained. MaptunerX features a full color, touch screen display, ability to restore stock tune settings and access to RIVA's complete tuning library and technical support.

RIVA Power Filter is installed. Power Filter Kit dramatically increases air flow to your supercharger via a large 4" diameter intake duct and oversized K&N filter element delivering greatly improved acceleration and top speed. Ducting is precision formed from a race proven composite that will not conduct heat to incoming air. Installs securely to supercharger via a tapered velocity stack, silicone coupler and stainless steel clamps. Includes pre-filter element.

NOTE: Sea-Doo and RIVA both strongly recommend the use of premium octane (91+) pump fuel in your craft.
