Silencer Box for Nissan X-Trail: Silicone
This silencer box for the Nissan X-Trail is specified around silicone, 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 inconsistent hardness between lots, or packing that arrived crushed at the port. Both are specification problems, and both are preventable.
