Sakura A-31220 Air Filter for Audi A4 (B8), A5 & Q5 | Premium Soft PU Frame Intake | Replaces 8K0133843E & 8R0133843C

Maintain the legendary performance and fuel efficiency of your Audi with the Sakura A-31220 Air Filter. Specifically designed for the Audi A4 (B8 platform) and the Q5 SUV, this filter is critical for protecting high-precision TFSI and TDI engines. Modern Audi powerplants utilize sensitive sensors and turbochargers that require an absolute seal and unrestricted airflow to function at peak capacity.

The A-31220 features a high-grade Soft PU (Polyurethane) Frame.³ In the high-temperature environment of a turbocharged Audi engine bay, this Soft PU frame acts as a high-compression gasket. It creates a vacuum-tight seal within the factory airbox, absorbing engine vibrations and preventing “dirty air bypass.” This specialized construction ensures that the Mass Air Flow (MAF) sensor remains free from dust contamination, preventing “Check Engine” lights and ensuring optimal fuel combustion.
