The Injen SP cold air intake for 2009–2020 Nissan 370Z 3.7L V6 replaces the factory intake with dual 6061‑T6 aluminum tubing and a serviceable SuperNano‑Web dry filter to increase airflow and deliver a louder intake tone. Injen's MR and Air Fusion technologies produce dyno-proven gains—up to about 15 hp and 11 lb‑ft—while maintaining safe A/F ratios. Fits standard 370Z models (excludes NISMO); CARB EO applies to 2009–2013 model years.
