The Injen SP1968P is a polished aluminum cold air intake for the 2007-2012 Nissan Sentra SE-R Spec-V with the 2.5L four-cylinder. It replaces the factory airbox with a mandrel-bent 6061-T6 tube and an open cone filter, and Injen claims its patented tuning (MegaRam, Air Fusion) adds power while keeping air-fuel ratios safe. It suits owners who want a louder intake sound, an engine-bay show piece, and a modest performance bump. Against rivals like AEM and K&N, it is a more expensive, tuner-focused option with a polished finish; owners like the sound and look but some report fitment hassles and check-engine lights if the MAF is not seated right.

Owners of the Injen SP intake for the Sentra SE-R Spec-V generally praise the sound, the polished look, and a modest power gain. Complaints center on fitment, heat soak from the open filter, and occasional check-engine lights after installation.
This cold air intake is a direct-fit replacement for the 2007-2012 Nissan Sentra SE-R Spec-V with the 2.5L L4 engine. It is for manual transmission vehicles only. It is part of Injen's SP series and uses Injen's patented MegaRam (MR) Technology.
The intake tube is 6061-T6 aluminum with smooth piping that removes restrictions and improves airflow. The kit includes a fully serviceable Injen SuperNano-Web dry air filter. This version has a polished finish.
Dyno-proven gains are up to 11 hp and 11 lb-ft of torque. The intake maintains safe air/fuel ratios and needs no additional tuning. It gives an aggressive engine tone under full throttle. It is made in Pomona, California, USA, and is covered by Injen's limited lifetime warranty.
