A Guide to Buying Genuine Vs Aftermarket Spare Parts

Original parts are generally made by the manufacturer that assembled your car, and offer better quality and fit than aftermarket parts, and will often last for a longer period of time or cheaper to repair, and may have warranties provided by the party who assembled the auto in the first place.

But they are usually more costly than aftermarket parts; so ultimately it comes down to your budget and whether the warranty gives you a warm fuzzy feeling.


Genuine parts are manufactured by your car’s manufacturer and will be the same parts used when your car was manufactured at the factory on the assembly line. Genuine OEM replacement parts are more expensive than aftermarket replacement parts, but they also fit and quality better.

They are aftermarket replacement parts created by independent manufacturers who are not related to the manufacturer of the vehicle from which the part is taken. That manufacturer may create them to the same OE technical specification or they may build the part to exceed the original, perhaps in terms of strength or energy efficiency. Some of these manufacturers are excellent, selling high-quality parts, while others create poor versions that are shockingly inexpensive but won’t last as long.

Generally speaking, repair as per the manufacturer’s instructions, with original equipment manufacturer (OEM) parts: when it’s under a manufacturer warranty or repair plan from your insurance company, you should adhere to these recommendations, certainly for any repairs that could receive warranty coverage benefits. Using aftermarket parts will void your warranty or make it less valuable if you end up needing to sell it or claim on this warranty down the road.


Original parts have manufacturer guarantees, and they often have manufacturer branding or vehicle-maker logos telling you they are the same part as the one that was in the car originally; these are the original equipment (OE) parts.

Aftermarket components are made by many different companies and do not necessarily carry the vehicle manufacturer’s brand. The specifications of aftermarket parts are typically identical to OEM components but their logo is different.

First and foremost, there is a common misperception that having something other than the original equipment replace a defective part will void your car warranty or insurance policy. The truth is that many manufactures of aftermarket parts are just as decent a quality as the original equipment parts, with different fixes or enhancements not incorporated into those parts by the original manufacturers – such parts are hopefully better and long-lasting than the original equipment parts. Lower quality and less reliable manufacturers might make the opposite type of parts – junk just doesn’t fit as well or last as long.

Genuine spare parts will guarantee top performance of your equipment and lessens the need for repairs in the future. Buying genuine spares will also save you on repairs in the future!

But while some of these parts are outright replacements for original spec, others differ greatly. They are aftermarket parts from other brands, designed to be fitted into your car with some modifications by your garage – which can be costly.

These parts if fitted to the right way, within factory service parameters, your focus (mainly to drive safely) will be maintained and this is the point at where you keep your vehicle for the best driving experiences.
