aFe Power MagnumFORCE Stage-2 Si Cold Air Intake System Pro DRY S for 2009-2015 Audi & VW (L4-2.0L) 51-81711

Fits select 2009-2015 Audi A3 and Volkswagen Beetle, Golf, Jetta, and Passat (L4-2.0L).

Upgrade your TDI engine's breathing with the aFe Power MagnumFORCE Stage-2 Si cold air intake system. This sealed intake (Si) is designed to replace the restrictive factory airbox with a high-flow, heat-insulating rotomolded plastic housing and intake tube. The cross-linked polypropylene construction resists heat soak while the integrated ram air scoop captures fresh, cool air from outside the engine bay. This configuration results in a 56% increase in airflow compared to the stock intake, improving throttle response and engine efficiency.

This system features the oil-free Pro DRY S filter, a 360-degree flow, washable, and reusable air filter that provides maximum convenience and protection without the need for filter oil. The precision-molded plastic intake tube is engineered to maximize airflow volume and velocity for consistent power gains across the RPM range.
