Injen 09-11 Acura TSX 2.4L 4cyl Black Cold Air Intake

If you're looking to give your 2009-2014 Acura TSX 2.4L engine a bit more breathing room, this Injen SP Series cold air intake is a solid option. It's designed to replace your restrictive factory airbox with a smooth, uninterrupted path for air to reach the engine, which can lead to noticeable improvements in horsepower and torque. Injen has been a well-known name in intake tuning for a long time, holding several patents on their process to ensure the intake works well with your car's computer without needing extra tuning.

The intake tube itself is made from 6061-T6 aluminum, which is strong and lightweight, and Injen has designed it to maintain a safe air-fuel ratio while improving airflow. It comes with a serviceable SuperNano-Web dry air filter that offers good filtration and increased surface area for more air. You'll also notice a more aggressive engine tone when you step on the gas, adding a bit of auditory excitement to your driving experience. This kit is made in Pomona, California, and includes Injen's limited lifetime warranty.
