Why is it important to use genuine Ford parts in my Transit Custom?

I've been using aftermarket parts in my Ford Transit Custom, but I've heard that it's important to use genuine Ford parts. Can anyone explain why and what are the benefits of using genuine parts?

As a long time Ford owner and enthusiast, I highly recommend using genuine Ford parts in your Transit Custom. Sure, aftermarket parts may be cheaper, but they can affect the performance and longevity of your vehicle.

Using genuine Ford parts is essential for maintaining the quality and reliability of your Transit Custom. They are designed specifically for your vehicle and have been tested and approved by Ford, so you can be confident in their quality.
