Product Description

The aFe Power TR-3021B-D Takeda Stage-2 Cold Air Intake System with Pro DRY S filter is a performance-oriented air intake upgrade designed specifically for 2013-2018 Nissan Altima models equipped with the 2.5L L4 (QR25DE) engine. This Takeda Stage-2 intake replaces the restrictive factory intake system with a high-flow design that improves airflow volume and velocity, resulting in enhanced throttle response and measurable horsepower and torque gains. The oil-free Pro DRY S synthetic filter media simplifies maintenance - just wash and reinstall without worrying about oiling. The vacuum-formed cover helps reduce hot under-hood air ingestion while presenting a stealthy appearance under the hood.

Installation is straightforward thanks to the direct bolt-on design using existing factory mounting points - no cutting, drilling, or permanent modifications are required. Included silicone couplers, clamps, and hardware make for a complete fitment, and the dyno-tuned intake tube is engineered to maximize airflow efficiency. While enhancing engine breathing and induction sound, this intake system is not CARB exempt and therefore cannot be shipped to or registered in certain states with stricter emissions rules. With aFe Power's 2-year limited warranty, the TR-3021B-D provides Altima owners a quality performance upgrade that balances airflow gains with everyday reliability.
