Product Details

If your 2009-2020 Nissan 370Z is feeling a bit restricted on air, this Injen SP Series cold air intake can help it breathe easier. This system is designed to replace your stock airbox and intake tubing with a smoother, more direct path for air to enter the engine. It’s a popular choice for drivers looking to get more performance out of their 3.7L V6 engine.

The heart of this Injen intake is its polished 6061-T6 aluminum tubing. This material is well-built and offers a smooth, uninterrupted path for air, reducing restrictions compared to the factory setup. Injen uses its patented MegaRam (MR) Technology and Air Fusion Technology, which are designed to tune the intake tract for optimal airflow and power gains while carefully maintaining a safe air-fuel ratio. This means you can expect a noticeable increase in horsepower and torque, often around 15 hp and 11 lb-ft, without needing to retune your ECU. The system also includes a serviceable SuperNano-Web dry air filter, which offers a large surface area for excellent airflow and filtration.

Beyond the performance improvements, this Injen intake also changes the sound of your engine, giving it a more aggressive and throaty tone under acceleration. The polished finish on the aluminum tubing looks sharp under the hood. Installation is designed to be straightforward, and the kit includes all the necessary hardware and instructions. Keep in mind that the CARB Executive Order for emissions compliance applies only to the 2009-2013 model years.
