Air Box for Toyota Corolla: Brass
This air box for the Toyota Corolla is specified around brass, 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 lead time that slipped twice before bulk started, or warranty claims traced back to a single lot. Both are specification problems, and both are preventable.
