PROX Air Filter for YAMAHA YFZ BANSHEE 350 1987-2006

On YAMAHA YFZ BANSHEE 350 from 1987 to 2006, the PROX 52.23087 air filter fits in place of the original part. Off-road, the engine breathes air full of dust. The oil-soaked foam filter traps the particles; worn or badly fitted, it lets through dirt that wears out pistons and cylinders.

Specifications

• Brand: PROX
• Manufacturer part number: 52.23087
• Engine: 2-stroke

When to replace it?

• Foam hardened, torn or coming away from its frame.
• Traces of dust behind the filter, in the intake boot.
• Filter that no longer gets its shape back after cleaning.

Clean and oil the filter after every dusty ride, and at least at the intervals given in the manual; replace it as soon as the foam hardens, tears or comes away from the frame. With two filters, you always have a clean one ready to go.

Fitting tips

1. Wash the filter with air filter cleaner, rinse it and let it dry completely.
2. Soak it in air filter oil, then squeeze out the excess without wringing the foam.
3. Lightly grease the sealing rim for a perfect seal.
4. Fit the filter flat on its cage, with no creases, and check that it seals all the way round.
