Toyota 4Runner 5th Gen 2010-2024, K&N 77 Series High-Flow Cold Air Intake System, Aluminum Tube

A 4Runner that hauls gear to the trailhead runs hard in heat and dust, and the factory air box limits airflow right when the engine needs it. A filter that needs constant cleaning adds to the load.

The K&N 77 Series replaces the factory air filter and intake tube with a mandrel-bent aluminum tube and an oversized oiled cotton filter. The filter needs cleaning only every 100,000 miles under normal highway driving, and installation does not void the vehicle warranty.

Pull the stock parts, fit the tube and filter, and tighten the clamps. Typical installation takes 60 minutes or less with simple hand tools.
