The AEM 21-513P Performance Cold Air Intake System is designed to produce horsepower and torque gains by replacing your vehicle’s restrictive factory air filter and air intake housing. This air intake system is designed, tuned and dyno-tested to fit specific Acura TL models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the previous air box space which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable chrome-like finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the replacement silicone breather hose. The cone 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). The air intake system is designed for easy installation with commonly available tools and it is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the AEM catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

Installation instructions could have been easier and black low resolution pictures didnt help much. Product definetly made the car sound beefier and gave it a deeper tone but with a slight whistle sound that I am not sure if it is normal, but doesn't sound nice. Product has been working fine so far.

This is a really nice cold air intake, I can hear the difference on the engine when accelerating. Makes a hard exhaust. I recommend this intake to anyone trying to gain power.
