SP Series Cold Air Intake

The Injen SP Series cold air intake system is engineered to enhance the performance of the 2003-2006 Nissan 350Z. Constructed from smooth 6061-T6 aluminum tubing, it eliminates intake restrictions, promoting improved airflow and an aggressive engine tone under acceleration. This cold air intake system is dyno-proven to deliver gains of up to 18 horsepower and 14 lb-ft of torque. It incorporates Injen's patented MegaRam (MR) Technology and Air Fusion technology to provide significant power increases while maintaining safe Air/Fuel ratios. No additional tuning is required for installation. Key features include a fully serviceable Injen SuperNano-Web dry air filter for enhanced filtration, and a 2-piece design that allows for conversion to a short ram system. The intake is available in Polished or Wrinkle Black finishes. It is directly compatible with 2003-2006 Nissan 350Z V6-3.5L models. Please note that this system does not fit 2007-2008 models.
