Product Description

The K&N 57S-9506 Performance Airbox is a direct-fit upgrade for 2012-2018 VW, Audi, SEAT and Skoda vehicles equipped with 1.2 L or 1.4 L 4-cyl engines. It replaces the restrictive factory airbox and intake assembly with a smooth-flow injection-molded airbox and a high-flow, washable cotton-gauze filter. This improved intake path reduces restriction and allows the engine to draw in more air, yielding a dyno-proven gain of around +6.4 HP under ideal conditions - resulting in sharper throttle response, better acceleration and noticeable torque improvement across the RPM range.

Installation is straightforward and uses factory intake hose connection - no cutting, drilling, or permanent modifications needed. The removable airbox lid makes filter servicing quick and easy, and the reusable filter reduces maintenance costs over time. Backed by K&N's No-Hassle Lifetime Limited Warranty, 57S-9506 is a reliable, long-lasting performance air intake upgrade for owners of compatible small-displacement VW-group 4-cyl engines who want improved responsiveness and airflow without compromising everyday drivability.
