Perrin Performance Cold Air Intake Hyper Pink Subaru STI 2016-2017 | PSP-INT-323HP

Overview

The Perrin Performance Cold Air Intake (PSP-INT-323HP) is a premium bolt-on upgrade engineered specifically for the 2016–2017 Subaru WRX STI. Designed to pull cooler, denser air from outside the engine bay, this cold air intake delivers measurable gains in horsepower, torque, and throttle response — all wrapped in Perrin's signature Hyper Pink finish for a show-quality underhood appearance. Whether you're building a track weapon or simply want more aggressive power delivery on the street, this intake is the ideal first performance modification for your EJ207-powered STI.

Key Features & Benefits

• True Cold Air Design — Draws air from outside the engine bay where temperatures are significantly cooler, improving air density and combustion efficiency for more power compared to short ram or factory intake systems.
• High-Flow Performance Filter — Perrin's oversized, reusable dry filter element flows more air than the restrictive OEM airbox, reducing intake restriction and boosting throttle response throughout the RPM range.
• Mandrel-Bent Aluminum Tubing — Aircraft-grade aluminum piping is precision mandrel-bent to maintain consistent inner diameter, eliminating turbulence-causing kinks that rob power and airflow velocity.
• Hyper Pink Powdercoat Finish — Perrin's durable Hyper Pink powdercoat is heat-resistant, corrosion-resistant, and UV-stable — making your engine bay stand out at shows and track days alike.
• Direct Bolt-On Fitment — Engineered to OEM mounting points on the 2016–2017 Subaru STI with no cutting, drilling, or permanent modifications required. Installs with basic hand tools in under 60 minutes.
• Heat Shield & Airbox Included — An integrated heat shield isolates the filter from underhood heat soak, ensuring consistently cool intake temps even in stop-and-go traffic.
• Reusable & Washable Filter — The high-flow filter is designed for long service life. Clean and re-oil periodically rather than replacing, reducing long-term ownership costs.
• Compatible with Perrin Accessories — Designed to work seamlessly with Perrin intercooler piping, blow-off valves, and other bolt-on upgrades for a fully integrated performance system.

Specifications

Fitment & Compatibility

This Perrin Performance Cold Air Intake is designed exclusively for the 2016 and 2017 Subaru WRX STI equipped with the EJ207 2.5L turbocharged flat-four engine. It is not compatible with the standard WRX (FA20DIT) or non-turbo Subaru models. Always verify your vehicle's year, trim, and engine code before purchasing. For model years outside 2016–2017, Perrin offers application-specific intake SKUs — contact us to confirm correct fitment for your build.

Is this intake CARB compliant? This intake is intended for off-road / closed-course competition use. It may not be legal for use on public roads in emissions-controlled states, including California. Please verify local regulations before installation.

Installation

The Perrin PSP-INT-323HP is a direct bolt-on installation requiring no permanent modifications to your STI. Most installations are completed in 45–60 minutes using basic hand tools. Remove the factory airbox and intake tube, install the Perrin heat shield to the OEM mounting points, connect the aluminum intake tube to the turbo inlet, and secure the high-flow filter. Perrin includes detailed instructions in the box. A post-installation ECU relearn (idle the vehicle for a few minutes after install) is recommended for optimal fueling. Professional installation is available but generally not required for this application.
