Using the wrong size DPF filter clamps will not create a sealing face at the DPF or DOC connection. This will result in exhaust leaks, inaccurate back-pressure readings, active fault codes, regeneration failures, and potential non-compliance with emissions. In the worst cases, these exhaust gases passing around the filter substrate will cause irreversible damage to the DPF. Always verify the part number before installation.
