Fitment guarantee and VIN verification

Each heat shield undergoes a shape inspection to check for deformation, the condition of the body mounting points, and the cleanliness of the heat-reflective surface.

Fitment tip: Heat shields for the tunnel in the MLBevo platform are profiled for a specific exhaust and drive shaft layout. Before purchasing, we recommend comparing the OE number stamped on the old heat shield or verifying compatibility using the vehicle's VIN.
