K&N YA-4504 High-Flow Air Filter | 2004-2010 Yamaha YFZ450/450R

Boost your Yamaha YFZ450's power with the K&N YA-4504 air filter. Washable, reusable, and designed for high airflow in dusty off-road conditions.

This performance air filter is designed to provide increased horsepower and torque by allowing more air into your engine while maintaining exceptional filtration. It features K&N's signature pleated cotton media, which provides a large surface area to capture dust and debris without restricting flow. Built for the rigors of off-road riding, it fits directly into your OEM air box and is pre-oiled and ready to install.

Best Uses

  1. Off-Road Trails & Sand Dunes: Ideal for extended trail riding and high-speed dune carving where heavy dust, sand, and silt are constant threats to the engine.
  2. Competitive ATV Racing: Perfectly suited for closed-course or cross-country racing where maximizing throttle response, horsepower, and torque is crucial.
  3. High-Altitude Riding: Engineered to provide clean, unrestricted carburetion or fuel injection management even when operating at fluctuating mountain altitudes.

Features

  1. Oiled Cotton Gauze Media: Features multiple layers of woven cotton fiber treated with specialized air filter oil to capture microscopic contaminants without choking airflow.
  2. Pleated High-Flow Design: Constructed with deep pleats that maximize the total filtration surface area, allowing low restriction and long service intervals.
  3. Direct Drop-In Fitment: Precision-molded to fit seamlessly into the stock Yamaha factory airbox with zero custom tools or fabrications required.
  4. Flexible Urethane Frame: Built with a highly durable, pliable perimeter and integrated sealing bead that blocks debris from bypassing the filter element.
  5. Washable & Reusable: Designed to be easily cleaned with K&N Power Kleen cleaner and re-oiled for continuous, lifetime performance.

Benefits

  1. Increased Horsepower & Torque: Optimizes the engine's combustion efficiency by supplying a greater volume of clean oxygen, boosting overall acceleration.
  2. Superior Off-Road Engine Protection: Protects sensitive internal engine components like pistons, valves, and cylinders from abrasive trail dust and sand.
  3. Cost-Effective Lifetime Savings: Eliminates the need to ever purchase another disposable filter, saving significant money over the lifespan of your ATV.
  4. No Jetting Adjustments Required: Under normal conditions, it drops right into your system and provides clean carburetion without needing immediate jet or fuel map changes.
  5. Eco-Friendly Performance: Reduces environmental waste by replacing throw-away paper and foam elements with a sustainable, long-lasting soluti
