Injen 03-06 G35 AT/MT Sedan Polished Cold Air Intake

If you're looking to get a bit more power and a more aggressive sound out of your 2003-2006 Infiniti G35 Sedan, this Injen RD Series cold air intake is a solid option. It's designed to replace your restrictive factory airbox and tubing with a smoother, more direct path for air to enter the engine. This means your engine can breathe easier, which often translates to a bit more horsepower and torque, especially in the mid-range where you'll feel it most.

The heart of this system is the mandrel-bent 6061-T6 aluminum tubing. Mandrel bending means the tube keeps a consistent diameter throughout its bends, unlike crush-bent tubing which can create restrictions. This smooth path helps pull in cooler, denser air from behind the front bumper, which is better for combustion. It also includes a serviceable Injen SuperNano-Web dry air filter that offers good airflow and filtration. You'll also notice a more throaty, aggressive engine tone when you step on the gas.

This kit comes with everything you need for installation, including the tubing, filter, hoses, and hardware. Injen backs this intake with a limited lifetime warranty, and it's CARB certified, meaning it meets emissions standards for many areas. It's a well-built piece that's made in the USA.
