Injen 07-09 Altima 4 Cylinder 2.5L w/ Heat Shield (Automatic Only) Black Short Ram Intake

If your 2007-2012 Nissan Altima with the 2.5L 4-cylinder engine needs a breath of fresh air, this Injen SP Series Short Ram Intake is a solid option. It's designed to let your engine take in more air, which can lead to improved performance and a more satisfying engine sound, especially when you step on the gas. This system is specifically tuned for your Altima, using Injen's patented MegaRam (MR) Technology and Air Fusion Technology to ensure safe air-fuel ratios while maximizing airflow.

The intake tube itself is made from 6061-T6 aluminum, offering a smooth path for air to enter the engine, reducing restrictions compared to the factory setup. It comes with a custom-designed heat shield to help keep engine heat away from the intake air, and a serviceable SuperNano-Web dry air filter that provides good filtration and airflow. You'll likely notice a more aggressive engine tone under acceleration, and Injen dyno-tested this system to show gains of over 10 horsepower and 11 lb-ft of torque.

This kit includes everything needed for installation, including the tubing, filter, heat shield, and hardware. It's designed as a direct fit for automatic transmission models, so no additional tuning is required to get the benefits. Injen also backs this intake with a limited lifetime warranty.
