RIVA Yamaha 2021+ GP1800R SVHO Power Filter Kit

Our Power Filter feeds your supercharged engine a steady diet of cool air delivering greatly improved acceleration and rpm. Replaces restrictive stock air box with a high-volume, precision-formed intake duct that attaches to the supercharger via a large 4" adapter. 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 for safety and reliability.

Key Features:

• Delivers increased acceleration & power.
• Stainless-steel screen type flame arrestor.
• Large 4" ducting attaches to supercharger via flow-matched velocity stack.
• Fits 2021 & Newer Supercharged GP models.
• IJSBA legal for all classes.
• Certified to meet U.S. Coast Guard 'SAE J1928' requirements.

NOTE: Our testing has determined the stock ECU will compensate for the increased air flow provided by our Power Filter Kit. For heavy surf use we recommend the use of our water-repellentf pre-filter. Part# RK13090PF-BK.
