VW Beetle | EGR Filter for AJ engine | 043 131 617B

The EGR filter (043 131 617B) ensures that exhaust gases are returned to the intake manifold in a controlled manner, reducing emissions and making the mixture more stable. In the AJ engine, this filter is an important part of the emission control system, especially relevant if your Beetle needs to pass inspection. Replace it during a service or when overhauling the system, and combine this with new intake and exhaust gaskets for a thorough inspection.
