AEM 21-8504DC Gun Metal Brute Force Intake System

Upgrade your Nissan Frontier, Xterra, or Pathfinder with the AEM 21-8504DC Brute Force Air Intake System, engineered to deliver increased horsepower and torque by replacing the factory air intake components. This system has been carefully tuned, dyno-tested, and designed specifically for select Nissan models. It features an oversized AEM Dryflow synthetic air filter for superior airflow and filtration, which is mounted in the original air box location and protected by a custom heat shield to reduce intake air temperature and optimize performance. The intake tube is constructed from mandrel-bent aluminum with a rugged gunmetal gray powder-coated finish, ensuring durability and a high-performance look. This system is designed to integrate with factory emissions equipment, including the mass airflow sensor and crankcase vent hose. The reusable Dryflow filter can last up to 100,000 miles between cleanings, depending on driving conditions. Backed by AEM’s Lifetime Limited Warranty, this system offers both performance and reliability in a simple bolt-on upgrade.
