Sea Doo Yamaha Universal 4 inch Titanium Intake Filter Kit

Built exclusively for harsh marine saltwater environments, this 4 inch universal filter kit replaces restrictive factory airboxes on nearly all mainstream Sea Doo and Yamaha jet ski series. Its oversized tapered cone structure expands air intake volume while cutting internal airflow resistance drastically.

The multi-layer hydrophobic filter media repels splashing seawater and traps sand, floating sediment and airborne grit to shield Rotax and Yamaha marine engines from premature wear. The built-in flame arrestor structure complies with marine safety standards, eliminating fire risks from engine backfire.

All sealing rings and mounting clamps adopt anti-corrosion stainless steel, resisting rust after long-term saltwater exposure. The 4 inch standard inlet design matches aluminum, carbon fiber and silicone intake piping universally, requiring only simple clamping installation without hull drilling or permanent modification.

The filter element is fully detachable, washable and reusable. Owners only need water-based cleaning instead of frequent part replacement, greatly lowering long-term maintenance costs. It brings snappier throttle response, higher peak RPM and a deeper sporty induction tone during full-throttle acceleration, ideal for stock and modified supercharged PWC builds.

5 Bullet Points
