Why is it so important to use Toyota parts?

In a word, Quality! We’ve yet to find an aftermarket part that matches a Toyota part in quality. Very few independent garages use original Toyota or Original Equipment (O.E.) parts to the extent that we do. Car manufacturers, like Toyota make many of the parts necessary to build their cars themselves but they also rely on outside suppliers for most parts. For example, Toyota uses transmissions and various engine parts made by Aisin, Denso supplies most of the electrical components (starters, alternators, fuel systems, switches), KYB makes many of their suspension pieces. These companies make many of their parts available to us through their distributors at a somewhat lower cost than what we can buy them from Toyota for. This allows us to keep our costs down and pass the savings on to our customers.
