Injen 04-06 Altima 3.5L V6 Polished Cold Air Intake

When you open the hood of your 2004-2006 Nissan Altima with the 3.5L V6, you'll see a polished aluminum intake tube, a SuperNano-Web dry air filter, and all the necessary hardware to get it installed. This Injen SP Series cold air intake is designed to let your engine breathe easier, which can lead to more horsepower and torque. Injen holds patents on their tuning process, meaning this intake is designed to work with your car's computer to maintain a safe air-fuel ratio while improving performance.

The intake tube is made from 6061-T6 aluminum, shaped to provide a smooth, uninterrupted path for air entering the engine. This design helps reduce restrictions compared to the factory airbox. The included SuperNano-Web dry filter is serviceable, meaning you can clean and reuse it, and it offers a large surface area for better airflow and filtration. Injen claims dyno-proven gains of up to 16 horsepower and 19.4 lb-ft of torque with this system, and it also changes the engine's tone to a more aggressive sound under acceleration.

This kit is designed as a direct fit for your Altima and doesn't require any additional tuning. It also has the flexibility to be converted into a short ram intake if you prefer. Injen backs this intake with a limited lifetime warranty.
