Description

The AEM 21-778C Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is relocated to be in driver-side wheel well which is designed to reduce intake air temperature and increase horsepower. The lower air intake tube is a free-flowing, mandrel-bent aluminum tube with a durable gunmetal gray powder coat finish. The upper air intake tube is a roto-molded, aerodynamically engineered, HDPE tube that insulates the cooler intake air from heat as it passes through the engine bay and into the engine's throttle body. This air intake system was developed to accommodate the Lancer's factory emissions control devices including the mass airflow sensor and PCV hose. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions).

Features & benefits

  • Precision-tuned and dyno-validated to enhance throttle response, sharpen acceleration, and improve overall engine efficiency, helping maximize horsepower and drivability.
  • Creates a deeper, more aggressive induction tone that highlights the intake system’s improved airflow.
  • Features low-restriction intake tubing that increases air velocity and high-volume airflow for maximum performance gains.
  • Equipped with a long-life, high-capacity air filter capable of up to 100,000 miles before servicing (depending on driving conditions), reducing maintenance while maintaining strong, clean airflow.
  • Utilizes washable, reusable, oil-free synthetic filter media that preserves airflow efficiency, traps harmful contaminants, and provides long-term value over disposable filters.
