K&N Engine Air Filter KNA-2326 — Long-Life 18,000 Mile Replacement for Toyota/Lexus/Scion, Direct-Fit High-Flow

The K&N KNA-2326 is a long-life engine air filter engineered to deliver up to 18,000 miles of reliable filtration and protection for select Toyota, Lexus, Scion and Pontiac vehicles.

Built by K&N — a leader in performance air filtration since 1969 — this premium replacement air filter is designed as a direct-fit upgrade for specified factory air boxes. It uses a synthetic or advanced cellulose-blend media depending on the application, offering high-efficiency particle capture while maintaining proper airflow. The KNA-2326 meets or exceeds OEM fit and performance expectations and installs quickly with basic hand tools.

How does this filter protect my engine without restricting airflow?

The KNA-2326 balances filtration efficiency and airflow by using a proprietary premium media that traps contaminants while allowing necessary air volume to reach the engine. That helps maintain combustion performance and throttle response similar to stock filters.

• Up to 99% particle capture of common contaminants
• Media engineered for airflow-to-filtration balance
• Direct-fit design preserves factory intake path

How long will the K&N KNA-2326 last compared to standard filters?

This Advantage Plus filter is rated for an extended service interval of 18,000 miles under normal highway driving — about 50% longer than many 12,000-mile disposable filters. The longer interval reduces replacement frequency and maintenance hassle while providing continuous protection.

• Rated life: 18,000 miles under typical driving conditions
• Approximately 1.5 years between changes at average annual mileage
• 1-year limited warranty included for added peace of mind
