Upgrade your Acura TLX with the AEM C.A.S 15-20 Cold Air Intake System, designed to boost horsepower and torque by replacing the factory air filter and intake housing. This system features an oversized AEM Dryflow synthetic washable air filter that delivers outstanding airflow, filtration, and performance. The filter is housed within the original air box space and protected by a heat shield, which helps reduce intake air temperature to maximize engine power and efficiency. The mandrel-bent aluminum intake tube, finished in a durable gunmetal gray powder coat, ensures optimal airflow and durability. Developed to work seamlessly with the vehicle's factory emissions control devices, including the mass airflow sensor and breather tube, this intake system maintains factory compliance and reliability. The synthetic filter media is oil-free and designed for long service life, capable of providing up to 100,000 miles of use before cleaning, depending on driving conditions. Installation is straightforward using common tools, making it a practical upgrade for enthusiasts seeking increased engine performance. Backed by AEM's Lifetime Limited Warranty, this cold air intake system is a reliable choice for enhancing your Acura TLX's power and acceleration. Please verify vehicle fitment and legal status in your state, as some AEM intake systems are not California legal, while others meet 50-state requirements.
