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

If you're looking to give your 2009-2014 Acura TSX 2.4L engine a bit more breathability and power, this Injen SP Series cold air intake is a solid option. It's designed to replace your restrictive factory airbox and tubing with a smoother, more direct path for air to enter the engine. This means your engine can take in more air, which is essential for combustion and generating power.

The heart of this system is the polished 6061-T6 aluminum tubing, which offers a smooth, uninterrupted flow path. Injen uses its patented MegaRam (MR) Technology and Air Fusion Technology, which they say helps tune the intake for optimal performance gains while keeping the air-fuel ratio safe. You'll also get a fully serviceable Injen SuperNano-Web dry air filter, which has a large surface area for good airflow and filtration. This intake is designed to be a direct fit, meaning no extra tuning is required after installation.

Beyond the performance improvements, you can expect a more aggressive and throaty engine tone under acceleration. Injen backs this intake with a limited lifetime warranty, giving you peace of mind.
