Air Filter for Geely Coolray: Carbon Steel
This air filter for the Geely Coolray 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 premature wear on the first batch, or a specification nobody had written down. Both are specification problems, and both are preventable.
