Toyota Tacoma 4th Gen 2024-2025 & 4Runner 6th Gen 2025, K&N 77 Series Cold Air Intake System, Aluminum Tube

The 2.4L turbo in the new Tacoma and 4Runner gives up airflow through a restrictive factory intake. Heat soak in the engine bay and a loaded trail rig compound the loss.

The K&N 77 Series replaces the factory intake with a mandrel-bent aluminum tube, a custom heat shield and a washable High-Flow LIFETIME oiled cotton filter. K&N lists estimated gains of up to 15.28 HP and 25.3 lb-ft from wheel-based dynamometer testing, and the filter needs cleaning only every 100,000 miles.

Remove the stock parts, fit the tube, shield and filter, and clamp the connections. Dyno reports are included with each system.
