Should I use OEM or aftermarket parts?
Both can be the right choice. OEM (original equipment) parts are made to the manufacturer's spec and fit exactly, which matters most for sensors, electronics and some engine parts. Premium aftermarket parts from reputable brands often match or beat OEM for brakes, suspension and filters. The parts to avoid are the cheapest no-name options, which are where fit and lifespan problems come from. A good shop will explain the trade-offs and let you choose.

We'll give you the options for the part, explain how they differ in fit, lifespan and warranty, and let you choose. Customers have appreciated being offered more than one brand for something like brake pads, along with a plain explanation of the difference.
From drivers who came to us
I brought my 2017 4Runner to them to have the front brake pads replaced and rotors resurfaced. They provided accurate quotes and gave multiple brand options for replacement parts.

More questions
Will aftermarket parts void my warranty?
No. Under the Magnuson-Moss Warranty Act, a manufacturer can't void your warranty for using aftermarket parts unless the part caused the failure. More on warranties.
What's the difference between OEM and OE?
OEM usually means the part comes in the carmaker's box. OE or "OE supplier" parts are made by the same company that supplies the factory, sold under their own brand.
Which parts should always be OEM?
We often recommend OEM for some sensors, like oxygen and airflow sensors, certain electronics, and parts where aftermarket fit is known to be poor for a specific car.
