Genuine factory equipment parts - there is a difference:

Safety
Manufacturer original equipment parts are made from the same stamping dies used in the production of your vehicle. The manufacturer performs impact tests on vehicles like yours to ensure that every part is a perfect fit and meets or exceeds vehicle safety standards.

Warranty
Genuine original equipment parts are the only collision repair parts covered by manufacturer warranty—generic aftermarket and salvage parts are not. Worse yet, if use of an aftermarket or salvage part causes damage to wiring or air bag deployment, you could be placing more than your warranty in jeopardy.

Resale Value/Lease returns
Keeping your vehicle "like new" helps ensure that you´ll get the greatest return on your investment at the time of resale. If you lease your vehicle, you will be expected to return it "up to standard" – otherwise you may be required to pay additional termination charges. Genuine, manufacturer-original parts help protect you and your investment.
