RIVA Yamaha FX SVHO Power Filter Kit for 2019 and Newer Supercharged FX, 4 Inch Intake with Stainless Filter
SKU: RY13120-1
AVAILABILITY: In stock (5 items)
Package size: 35 x 25 x 15 cm | Weight: 1.5 kg
This RIVA Power Filter Kit replaces the restrictive stock air box on 2019 and newer supercharged Yamaha FX models with a precision-formed intake duct and an oversized stainless steel mesh filter. Cooler, freer air reaches the supercharger through a large 4 inch adapter for stronger acceleration and RPM.
It is aimed at FX SVHO, FX Cruiser SVHO and FX Limited SVHO owners who want a proven bolt-on power gain. RIVA states the stock ECU compensates for the added airflow; for heavy surf it recommends the waterproof pre-filter RK13090PF-BK, which we also stock.
