Product Description

The aFe Power Magnum FORCE® Super Stock Pro DRY S Intake System (Part #55-12551) is engineered specifically for 2014-2021 Toyota Tundra models equipped with the 4.6L or 5.7L V8 engines. This system enhances airflow while retaining the factory airbox, making it a stealthy yet effective performance upgrade. By combining a high-flow Pro DRY S synthetic filter, a mandrel-bent aluminum intake tube, and a Dynamic Air Scoop, the system improves airflow by approximately 13% over stock, helping deliver gains of up to +18 horsepower and +30 lb-ft of torque.

A key component of this system is the included Silver Bullet throttle body spacer, which uses a serrated/helix design to improve airflow velocity and combustion efficiency. The oil-free Pro DRY S filter provides excellent filtration with minimal maintenance, making it ideal for daily driving and performance use. Installation is simple with a direct bolt-on design requiring no cutting or drilling, and CARB compliance (EO# D-550-16) makes it legal for use in emissions-regulated states where applicable.
