At Genius Parts, we always supply genuine spares sourced directly from the manufacturer.

Due to manufacturers’ recycling and reclaiming processes, the condition of parts may be new or refurbished (like new) and equivalent in performance and reliability, but every item is fully tested, verified for performance, and guaranteed with the same warranty.

If you would like any clarification before ordering, please get in touch.
