Injen 06-08 M45 4.5L V8 Polished Cold Air Intake

If you're looking to give your 2006-2010 Infiniti M45 4.5L V8 a bit more pep, this Injen SP Series cold air intake is designed to help your engine breathe easier. By replacing the restrictive factory airbox with a smooth, polished aluminum tube, this system allows for a more direct path for cooler air to enter the engine, which can lead to improved performance and a more satisfying engine sound.

The heart of this Injen intake is the 6061-T6 aluminum tubing, which is shaped to provide an uninterrupted flow of air. Injen uses their patented MegaRam (MR) Technology and Air Fusion, which they say helps tune the intake for optimal power gains while maintaining a safe air-fuel ratio. This means you can expect a noticeable increase in horsepower and torque, with dyno tests showing gains of up to 13 hp and 10.8 lb-ft of torque. It also comes with a serviceable SuperNano-Web dry air filter that offers good filtration without needing oil.

Beyond the performance gains, you'll likely notice a more aggressive engine tone when you step on the gas. The kit includes everything needed for installation, and it's designed as a direct fit for your M45. Injen also backs this intake with a limited lifetime warranty.
