Perrin Performance Cold Air Intake Black Subaru STI 2016-2017 | PSP-INT-323BK

Overview

The Perrin Performance Cold Air Intake for the 2016–2017 Subaru WRX STI is an engineered performance upgrade designed to maximize airflow to your EJ257 engine. Purpose-built for STI owners who demand measurable power gains and a more aggressive induction sound, this black cold air intake replaces the restrictive factory airbox with a free-flowing system that pulls cooler, denser air from outside the engine bay. Backed by Perrin's motorsport-proven engineering heritage, this is one of the best cold air intakes available for the 2016-2017 Subaru STI.

Key Features & Benefits

• Increased Airflow – Larger-diameter intake tubing reduces restriction compared to the OEM airbox, allowing the engine to breathe more freely for improved throttle response and power output.
• Cooler Intake Temperatures – Cold air intake design sources air from a lower, cooler area of the engine bay, improving air density for a more efficient combustion cycle.
• Aggressive Induction Sound – Experience a pronounced turbo spool and induction roar that the stock airbox suppresses, giving your STI an unmistakable performance character.
• Durable Black Finish – High-quality construction with a sleek black finish that looks at home under the hood of any performance-built STI.
• Direct Bolt-On Fitment – Engineered specifically for the 2016–2017 Subaru STI with no cutting, drilling, or permanent modifications required.
• High-Flow Performance Filter – Includes a high-flow air filter designed to capture contaminants while minimizing airflow restriction for sustained performance gains.
• Perrin Motorsport Pedigree – Designed and validated by Perrin Performance, a trusted leader in Subaru performance parts with decades of track-proven engineering.
