K&N AirCharger 63-9034 Performance Air Intake for 2010-2024 Toyota 4Runner and FJ Cruiser (4.0L)

Fits 2010-2024 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser (4.0L).

The K&N AirCharger 63-9034 air intake system is engineered to replace the restrictive factory air filter and intake housing on your 4.0L V6 engine. By smoothing and straightening the airflow path, this system reduces intake restriction, allowing the engine to draw in a larger volume of cooler, denser air for improved throttle response and power delivery. The custom-molded intake tube connects directly to the throttle body, ensuring a precise fit and streamlined flow.

This kit features a chrome-topped K&N high-flow air filter and a dedicated heat shield designed to install into the original air box location, protecting the intake charge from radiant engine heat. The oversized filter is washable and reusable, capable of lasting up to 100,000 miles between cleaning services depending on driving conditions. Installation is straightforward and can be completed in approximately 90 minutes using standard hand tools like a socket set, pliers, and wrenches.
