Toyota 4Runner 5th Gen 2010-2020, K&N 57 Series High-Flow Intake Tube and Air Filter Kit

A 4Runner that has to pass emissions rules in any state limits the intake choices. Drop-in parts that keep the factory air box make the upgrade simple.

The K&N 57 Series replaces the factory tube with a roto-molded HDPE intake tube and a direct replacement oiled cotton filter that drops into the factory air box. It carries a CARB EO number and is legal in all 50 states, and the filter needs cleaning only every 100,000 miles under normal highway driving.

Swap the tube and filter, tighten the clamps, and start the engine. Typical installation takes 60 minutes or less with simple hand tools.
