GMC Sierra 2500 Performance Air Intake - K&N Engineering - 77 Series - `11-`14. A direct-fit K&N 77 Series performance intake designed for 2011–2014 GMC Sierra 2500 models, engineered to improve intake flow while replacing the factory airbox and tube.
This K&N intake uses a mandrel-bent aluminum intake tube and a washable, reusable High-Flow air filter with oiled cotton media to increase airflow and improve throttle response. The oversized conical filter is built for long service intervals under normal highway driving, and many kits include a custom heat shield or air box to reduce intake temperatures from the engine bay. Installation is a straightforward bolt-on process that typically takes less than 90 minutes and requires common hand tools. Check the product specifications for CARB compliance status for California emissions-controlled vehicles.
