The Injen SP short-ram intake for 2007–2009 Nissan Altima 2.5L (automatic only) is a polished intake system that improves airflow and throttle response. It uses 6061-T6 aluminum tubing, a serviceable SuperNano-Web dry filter and includes a heat shield built for the application. Injen’s MR and Air Fusion technologies are incorporated, and dyno-proven gains near ten horsepower are documented along with the manufacturer’s limited lifetime warranty.
