Unleash the true potential of your Honda Civic SI or Acura ILX with the AEM 21-685C Performance Cold Air Intake System. Expertly engineered for performance enhancement, this system replaces the restrictive factory air filter and intake housing, resulting in tangible gains in horsepower and torque. Crafted from mandrel-bent aluminum, the intake tubing showcases a robust gunmetal gray powder-coated finish, ensuring both durability and a sleek aesthetic.

Performance isn't just engineered; it’s crafted and tested. Our team has meticulously designed and dyno-tested the AEM 21-685C to ensure it perfectly fits specific Honda and Acura models. Drawing air efficiently is paramount; hence, our system features an oversized AEM Dryflow synthetic washable air filter known for impressive air flow and filtration performance. Strategically relocated to the driver’s side wheel well, the air filter helps in lowering intake air temperature, directly translating to more horsepower.

At AEM, we understand the importance of meeting emissions compliance without sacrificing performance. The 21-685C system incorporates a seamless integration with the engine’s factory emissions control devices, including the mass air flow sensor and replacement silicone breather hoses. Drive confidently knowing our air filter, composed of oil-free synthetic filter media, can perform up to 100,000 miles before requiring cleaning, dependent on driving conditions. Furthermore, it is backed by AEM's Lifetime Limited Warranty, underscoring our commitment to quality and your peace of mind.
