Fits select 2009-2013 Infiniti FX35 and FX37 Base (3.7L).

Relieve your engine's intake restrictions with the Injen SP Series performance intake. As the flagship system in Injen's lineup, this dual short ram intake is engineered using mandrel-bent 6061-T6 aluminum to provide a smooth, uninterrupted path for high-velocity airflow. By utilizing patented MegaRam (MR) and Air Fusion Technology, this system is precisely tuned to maintain safe air-fuel ratios while delivering significant performance increases across the power band.

This kit features dual Injen SuperNano-Web dry air filters, which offer superior filtration and increased surface area without the need for filter oil. To protect against engine bay heat soak, the system includes application-specific heat shields. Beyond the performance gains, you can expect an aggressive, throaty engine note under acceleration. Made in Pomona, California, this system is a direct-fit upgrade that requires no additional ECU tuning for operation.
