Product Details

When you open the hood of your 2003-2006 Nissan 350Z, you'll see a polished SP Cold Air Intake System. This kit includes the intake tubing, a serviceable SuperNano-Web dry air filter, and all the necessary hardware and instructions to get it installed. It's designed to let your 3.5L V6 engine breathe more freely, which can lead to noticeable improvements in performance.

The heart of this system is the 6061-T6 aluminum intake tube. It's shaped to provide a smooth, uninterrupted path for air entering the engine, reducing restrictions compared to the stock setup. Injen has also incorporated their patented MR Technology, which helps tune the intake for safe air-fuel ratios while maximizing power gains. This means you can expect an aggressive, throaty engine tone under acceleration and a solid boost in torque, with dyno results showing up to 18.3 more horsepower and 14.0 ft-lbs of torque.

Beyond the performance gains, Injen backs this intake with a limited lifetime warranty and it's made right here in Pomona, California. The included SuperNano-Web dry filter is fully serviceable, meaning you can clean and reuse it for the life of the intake. Plus, the two-piece design allows you to convert it to a short ram intake if you prefer a different setup.
