When you're making repairs or performing maintenance on your BMW, you'll want to invest in Original Equipment Manufacturer parts - this is the term used to describe parts made by a main dealer. This means they're made with your specific car in mind, and while they generally are more expensive than aftermarket varieties, they are also considered to be of a much higher quality. You never quite know what you'll be getting with a third-party part - which should give you some hesitation when you're going to buy parts. You don't want to just "guess" when it comes to the parts you're installing in your vehicle. You want to know that the parts are going to fit your car accurately and give you high quality performance that lasts a long time.
