Product Description

The aFe Power TR-4304P Takeda Retain Stage-2 Cold Air Intake System with Pro DRY S filter is a premium performance upgrade designed for Subaru Legacy and Outback models equipped with the 3.6L H6 Boxer engine for model years 2010 through 2014. This intake system replaces the restrictive factory intake with a higher-flow, sealed design that enhances airflow volume and velocity to the engine, resulting in improved throttle response and measurable gains in horsepower and torque. The oil-free Pro DRY S synthetic filter media is washable and reusable, simplifying maintenance without the need for filter oil.

Installation is straightforward with a direct bolt-on design that uses existing factory mounting points and includes all required hardware - no cutting, drilling, or permanent modifications are required. The included sealed housing helps isolate the intake from hot engine bay air, promoting cooler air delivery and more consistent performance. With aFe Power's 2-year limited warranty and verified 50-state CARB compliance where applicable, the TR-4304P provides Subaru Legacy and Outback owners a reliable and effective performance upgrade with enhanced engine sound, throttle feel, and airflow efficiency.
