Injen SP Series Wrinkle Red Cold Air Intake for 2008-2013 Subaru WRX / STI (2.5L) - SP1204WR

Fits 2008-2013 Subaru Impreza WRX and WRX STI models equipped with the 2.5L turbocharged engine.

The Injen SP series is a flagship cold air intake system designed for drivers seeking measurable performance gains and a refined engine note. Built from mandrel-bent 6061-T6 aluminum, this system replaces the restrictive factory airbox with a high-flow intake path that optimizes air-fuel (A/F) ratios. It features Injen's patented MegaRam (MR) and Air Fusion technologies, which tune the intake tube to maintain safe engine parameters while maximizing power delivery across the entire RPM range.

This kit includes a custom-designed heat shield to isolate the intake from engine bay heat and a fully serviceable SuperNano-Web dry air filter. This synthetic media provides superior filtration efficiency and airflow without the need for filter oil. The wrinkle red finish provides a durable, high-end look that complements the Subaru engine bay.
