Injen 10-12 Mazda 3 2.5L-4cyl Polished Cold Air Intake w/ Silicone Intake Hose

When you open the hood of your 2010-2012 Mazda 3 with the 2.5L engine, you'll see a polished aluminum intake tube, a silicone hose, a SuperNano-Web dry air filter, and all the necessary hardware to get it installed. This kit is designed to let your engine take in more air, which can lead to a noticeable improvement in performance.

The main part of this system is the 6061-T6 aluminum tubing. It's shaped to give air a smooth, uninterrupted path into the engine, reducing restrictions compared to the stock setup. Injen uses their patented MR Technology and Air Fusion processes to help tune the intake for safe air-fuel ratios, so you get improved power without sacrificing engine health. You'll likely hear a more aggressive, throaty sound when you accelerate, and dyno tests show gains of around 6 horsepower and 8 ft-lbs of torque.

The included SuperNano-Web dry air filter is serviceable, meaning you can clean and reuse it, and it offers good filtration. This intake is designed as a direct fit, so no additional tuning is required after installation. It's also available in different finishes if you want to match your engine bay's look.
