K&N | High-Flow Replacement Air Filter for Toyota & Lexus Models - (2006-2026)

Optimize your engine's absolute volumetric efficiency and induction breathe with the K&N High-Flow Replacement Air Filter™ (Part No. 33-2381), engineered as the ultimate sustainable performance upgrade over restrictive factory paper elements. Manufactured featuring K&N's premium oiled-cotton multi-layered filtration grid (as illustrated in image_2938a3.jpg), this drop-in replacement panel filter significantly minimizes structural airflow resistance within the original equipment air box housing track. By allowing a continuous, high-volume stream of clean oxygen into the combustion chambers, it directly facilitates enhanced horsepower and sharper mid-range acceleration curves while providing heavy-duty physical defense against road grit and fine desert sand particles.

Directions for Use:

1. Ensure the vehicle's engine is fully switched off and cooled down, confirming fitment matching the application data.

2. Unclamp the securing spring-latches on the factory air box housing cover.

3. Pull out the dirty factory paper filter element.

4. Clean the interior seating tray of the airbox to clear any static surface dust or road debris.

5. Position the pre-oiled K&N performance panel filter flush onto the housing track, verify the flexible rubber seal perimeter is flush, and lock the air box cover tightly back into place.

Maintenance Profile:

This high-flow performance filter arrives pre-charged with genuine K&N filtration oil directly from the factory and is ready for immediate drop-in setup. To preserve peak mass flow efficiency across standard operations, routine cleaning and re-oiling with an official K&N Recharger assembly kit is recommended roughly every 80,000 kilometers (or sooner if driven consistently in severe desert environments).
