Cabin Filter for BMW 3 Series: EPDM Rubber
This cabin filter for the BMW 3 Series is specified around epdm rubber, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is a supplier who changed material without saying so, or inconsistent hardness between lots. Both are specification problems, and both are preventable.
