Perrin Red Cold Air Intake Fits 08-14 Subaru WRX / 08-17 STI

Dial up the sound, throttle response, and horsepower on your EJ25-powered WRX or STI with this cold air intake system from Perrin Performance. Designed specifically for the 2008–2014 WRX and 2008–2017 STI chassis, this intake offers serious performance gains without sacrificing drivability—making it a perfect foundation mod for anyone looking to extract more from their turbocharged Subaru.

The CNC mandrel bent aluminum tubing provides a smooth, unrestricted airflow path to the turbocharger, eliminating the turbulence and heat soak common in the OEM intake tract. The precise tubing diameter is tuned to maintain safe air-fuel ratios and strong MAF signal accuracy—critical for both stock and aftermarket ECU calibrations. Combined with Perrin's signature powder-coated finish, the system is corrosion-resistant, heat-tolerant, and visually stealthy or aggressive depending on your build.

The intake repositions the high-flow filter into a cool-air zone within the engine bay, reducing intake air temperatures and increasing oxygen density—translating to real-world power you can feel. Paired with tuning, expect noticeable gains in torque, throttle response, and mid-to-high RPM performance. The transformation is more than just numbers: the moment you get into boost, you’ll be rewarded with sharper spool sounds, deep intake growl, and that signature turbo surge that makes every drive more visceral.

Installation is direct bolt-on with no cutting or fabrication required, and the intake is compatible with most popular tuning platforms. Whether you're building for street, canyon runs, or track use, this is the kind of upgrade that pays dividends in performance and driving enjoyment.

• Mandrel bent aluminum construction for optimal airflow and durability
• Improved turbo spool and intake sound for a more exciting driving experience
• Relocates air filter to reduce heat soak and increase air density
• Powder-coated for corrosion resistance and stealthy under-hood appearance
• Maintains reliable MAF scaling for safe operation on stock or tuned ECUs

Perrin has earned a cult following among Subaru owners by delivering parts that not only perform, but do so with consistent engineering and attention to detail. Whether you’re adding your first mod or refining your build, Perrin’s intake is a smart investment in both power and driving excitement.
