Perrin Performance Cold Air Intake Red Subaru STI 2016-2017 | PSP-INT-323RD

Overview

The Perrin Performance Cold Air Intake (PSP-INT-323RD) is a premium bolt-on upgrade engineered specifically for the 2016–2017 Subaru WRX STI. Designed to replace the restrictive factory airbox, this cold air intake draws in cooler, denser air from outside the engine bay — delivering measurable gains in throttle response, horsepower, and turbo spool. Finished in an aggressive anhydized red, it's a performance and aesthetic upgrade in one.

Key Features & Benefits

• Cold Air Positioning — Pulls intake air from a low, cool location away from engine heat, maximizing air density for improved combustion and power output.
• High-Flow Filtration — Paired with a performance air filter that flows significantly more air than the OEM airbox, reducing intake restriction and boosting turbo efficiency.
• Anodized Red Finish — Durable hard-anodized aluminum construction resists corrosion and heat, while the bold red finish adds a clean, race-inspired look under the hood.
• Mandrel-Bent Aluminum Tubing — Smooth, mandrel-bent bends minimize turbulence and pressure drop for consistent, unrestricted airflow from filter to turbo inlet.
• Direct OEM Replacement Fit — Engineered to use factory mounting points and sensor ports, ensuring a precise, rattle-free fit with no cutting or drilling required.
• MAF & IAT Sensor Compatible — Pre-drilled ports accommodate factory Mass Air Flow (MAF) and Intake Air Temperature (IAT) sensors for seamless plug-and-play integration.
• Improved Turbo Response — Reduced intake restriction means the FA20DIT/EJ257 turbocharger spools faster, delivering stronger mid-range pull and more responsive power delivery.
• Reusable & Serviceable — The performance air filter is cleanable and reusable, offering long-term value over disposable OEM paper filter replacements.

What's Included

• Perrin Performance mandrel-bent aluminum intake tube (anodized red)
• High-flow performance air filter
• Cold air inlet scoop / heat shield (where applicable)
• All necessary hardware, clamps, and couplers
• Detailed installation instructions

Specifications

Fitment & Compatibility

The Perrin Performance PSP-INT-323RD cold air intake is designed as a direct-fit replacement for the following vehicles:

• 2016 Subaru WRX STI — All trims (sedan)
• 2017 Subaru WRX STI — All trims (sedan)

Note: Verify your vehicle's engine code and trim level before ordering. This intake is designed for the STI model with the EJ257 turbocharged engine. It is not compatible with the standard WRX (FA20DIT). Always confirm fitment using your VIN or consult a fitment guide.

Installation

The Perrin Performance Cold Air Intake is designed as a straightforward bolt-on installation for the 2016–2017 Subaru WRX STI, typically completable in 1–2 hours with basic hand tools. The intake uses all factory mounting points and sensor locations, requiring no cutting, drilling, or permanent modification to the vehicle. Perrin includes detailed step-by-step installation instructions. While this is a DIY-friendly upgrade, installation by a qualified mechanic is recommended if you're unfamiliar with intake system components. No ECU tune is required for installation, though an Accessport or equivalent tune is recommended to fully optimize power gains.
