Product Details

When you open the hood of your 2004-2006 Nissan Altima with the 2.5L 4-cylinder engine and automatic transmission, you'll see a polished aluminum intake tube, a SuperNano-Web dry air filter, and all the necessary hardware and instructions. This Injen SP Series cold air intake is designed to let your engine breathe easier, which can lead to a noticeable increase in horsepower and torque.

The heart of this system is the 6061-T6 aluminum tubing, shaped to provide a smooth, unrestricted path for air entering the engine. Injen uses patented technologies like MegaRam (MR) Technology and Air Fusion to ensure the intake is tuned for optimal performance and maintains a safe air-fuel ratio. This means you get the power gains without compromising your engine's health. The included SuperNano-Web dry filter is serviceable, meaning you can clean and reuse it, and it offers excellent filtration while allowing more air in. You'll also notice a more aggressive engine tone when you step on the gas.

This Injen cold air intake is a direct fit for automatic transmission models and doesn't require any additional tuning to see the benefits. It's also made in Pomona, California, and backed by Injen's Limited Lifetime Warranty.
