How to Choose the Right Replacement Part

Most replacement parts fall into one of three tiers. Original equipment (OE) parts are made by the same supplier that produced the part your vehicle left the factory with, and they carry the highest price. Original equipment equivalent parts are built to the same specification by a different manufacturer, which usually means the same fit and service life for noticeably less money. Economy parts trade some material quality or warranty length for the lowest price, which can make sense on an older vehicle you do not plan to keep.

For wear items like brake pads, rotors, filters and wiper blades, the tier matters less than replacing them on schedule. For parts that are labor-intensive to reach, such as water pumps, timing components and wheel bearings, paying for the longer warranty is almost always the cheaper decision over time, because the cost of doing the job twice dwarfs the price difference on the part itself.

Before you order, confirm the year, make, model and trim of your vehicle, and check whether the part differs by engine size, drivetrain or brake package. Front and rear, left and right, and upstream and downstream positions are not interchangeable. Every product page here lists the brand and manufacturer part number, so you can cross-reference the exact part you are replacing.
