K&N High-Flow Engine Air Filter for Toyota 2002–2020 (33-2281) — Washable, Reusable, Pre-Oiled

This high-performance replacement fits factory air boxes for models including 4Runner, Tacoma, Tundra, FJ Cruiser, Hilux, and Land Cruiser. Built with multiple layers of cotton gauze and a durable frame, the filter is pre-oiled and ready to install in minutes. It's designed for longevity—clean only every several years under normal driving conditions—and carries K&N's limited lifetime warranty, reducing ongoing replacement costs and landfill waste compared with disposable paper filters.

How does this filter affect my vehicle's performance?

By allowing more air into the intake while still trapping contaminants, this K&N element can help the engine breathe more efficiently. That improved airflow often translates into smoother throttle response and potential gains in horsepower and acceleration under many driving conditions.

• Engineered media increases airflow for better combustion efficiency
• Multi-layer cotton gauze captures dirt without restricting flow
• Pre-oiled and ready to install—no break-in required
• Tested on race tracks and road conditions for consistent results

How often will I need to clean or replace it?

This K&N filter is washable and reusable, designed to last the life of the vehicle when serviced correctly. Under typical highway driving, cleaning is recommended roughly every 75,000 miles; heavy-duty or dusty use requires more frequent inspection and maintenance.

• Clean approximately every 75,000 miles under normal highway driving
• Inspect sooner in dusty or off-road conditions
• Cleaning kits available that restore performance and extend life
• Reusable design eliminates frequent disposable replacements
