Cabin Filter Housing for Subaru Forester: Carbon Steel
This cabin filter housing for the Subaru Forester is specified around carbon steel, 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 reorders that did not match the approved sample, or a fitment that looked right on paper and failed on the bench. Both are specification problems, and both are preventable.
