Product Description

The aFe Power TR-4104P Takeda Retain Stage-2 Cold Air Intake System with Pro DRY S filter is a performance upgrade designed for Mazda RX-8 models equipped with the 1.3L rotary engine from 2004 through 2012. This intake system replaces the restrictive factory airbox with a short-ram design that improves airflow volume and efficiency, resulting in better engine breathing, throttle response, and measurable gains in horsepower and torque. The Pro DRY S synthetic air filter media is oil-free and washable, making filter maintenance easier and more convenient without the mess of oil-soaked media.

Installation is simple thanks to the direct bolt-on design that uses existing factory mounting points - no cutting or drilling required. Included silicone couplers, clamps, and hardware ensure a complete and secure installation. The clear-coat anodized polished aluminum intake tube enhances under-hood appearance while resisting oxidation and wear. With verified 50-state CARB compliance under EO# D-550-16 (where applicable) and backed by aFe Power's 2-year limited warranty, the TR-4104P provides a reliable and effective performance upgrade for RX-8 owners seeking increased airflow, improved throttle feel, and enhanced engine sound.
