OEM parts, or not?

Hey Zahntech --

So, I'm thinking about using an independent shop for my auto repair and maintenance, but I'm concerned that the shop will use sub-standard parts. I have a Lexus, and I want the real-deal Lexus parts. Can independent shops get them, and should I insist on them?

You're smart to be concerned about the quality of the parts you're getting, but you should have those concerns anywhere you go - dealership or independent shop. You can request from any shop that they use OEM (original equipment manufacturer) parts - independents can get them just like the dealerships. (In fact, most dealerships will sell parts at wholesale cost to the independent shops - they want to make money any way they can, too.)

However, there are times to insist on OEM parts and times not to. Oftentimes, the part itself isn't made by Toyota or Honda - it's made by a third-party and just re-branded. In these cases, sometimes going with the "OEM" part can actually cost you more - you can get the same thing in a plain white box for much less. Unfortunately, you're not going to know which parts are like this and which aren't - which is why (and we always get back to this point) you've got to trust your mechanic. He'll be able to look up the specs, the true OEM, and other information and know that you're getting the same high-quality part without the pretty little car manufacturer logo on it.

When the part is made by the auto company, often it's better quality. You don't have to go with Toyota brake pads - but they're likely to be the best ones for your vehicle. If you want to save money or splurge on the highest quality, your mechanic can work with you to figure out the best possible part for your problem. Maybe it's the OEM part, maybe not.

Now, if you have a high-end luxury car, like my favorite, the Acura NSX, you might be interested in special parts - drilled rotors, superchargers, and so on. In this case, you're definitely better off finding an independent shop - it's unlikely the dealership will do this kind of work.

You have the right to know what parts are going into your vehicle; if you have concerns, make sure you discuss them with your mechanic. I know us techs, we love talking about parts. You'll have trouble shutting us up once you get us going!
