Sakura A-31880 Cylindrical Air Filter for Audi A6 (C7) & A7 2.0L / 3.0L TDI | Premium Soft PU End Cap | Replaces 4G0133843

Maintain the smooth, high-torque delivery of your luxury sedan with the Sakura A-31880 Air Filter. Specifically designed for the Audi A6 (C7 Generation), this filter is built to handle the immense airflow demands of Audi’s TDI TwinPower Turbo engines. For executive sedans, air purity is not just about engine health; it is about maintaining the precision of the fuel injection system and the responsiveness of the turbocharger.

The A-31880 features a specialized Cylindrical Element with Soft PU (Polyurethane) End Caps. In the Audi C7 chassis, the airbox design utilizes a round filter to maximize the surface area within a compact space. The Soft PU end caps act as self-sealing gaskets, ensuring a 100% airtight fit that prevents “dirty air bypass.” This structural integrity is vital for protecting the Mass Air Flow (MAF) sensor and the high-precision compressor wheels of the turbocharger from microscopic abrasives.
