Three Reasons to Choose Genuine Car Parts Over Aftermarket Parts

 While we all endeavour to look after our cars as well as possible, it’s inevitable that they’re going to need some maintenance at some point during their lifetime.

Whether it’s normal wear or tear or a bump or crash, you usually have two options when your car needs repairs; you can either take it to one of the manufacturer’s official dealerships, or go to an independent garage.

While you might think both will use the same parts to repair your car, an independent garage will usually actually use ‘aftermarket’ parts, whereas the dealership will use OEM (genuine) ones.

So what are the benefits of opting for genuine car parts? We’re going to take a look at three reasons.


The most important benefit that genuine parts have over aftermarket alternatives is their quality.

While this isn’t to say that all aftermarket parts are of a low quality, it’s important to know how they are made.

While genuine parts are built in the same factory as the vehicle itself, and made specifically to fit it, aftermarket parts are built as multi-purpose parts, which will fit a number of different models.

To find out more, we spoke to a genuine Honda parts dealer, Cox Motor Parts, who said: “Each genuine part sold is precisely designed and rigorously tested, not only for its individual performance, but for its interaction with the entire vehicle as well.

“This process helps ensure that each part will function at its optimum performance level while providing the durability and reliability that you expect from your manufacturer.”


Of course, the quality of your parts is directly linked to safety, which is of the utmost importance for you and your family.

Because aftermarket parts don’t go through the same rigorous testing that genuine ones do, unfortunately you can never be guaranteed that your vehicle is as safe as possible.

Because the parts haven’t been made with your vehicle specifically in mind, they won’t quite work in tandem with the rest of the car as they should do.

While aftermarket parts might sometimes (but not always) work out cheaper, is it really worth putting your vehicle, and maybe even your life, at risk for?


Your vehicle will usually come with a warranty which will vary depending on the manufacturer and whether the car is new or used.

However, did you know that by having your vehicle fitted with aftermarket parts you might actually be putting your warranty at risk?

This is because aftermarket parts can be classed as modifications, and once your car is fitted with them, it’s no longer ‘as bought’, and its warranty could be voided.

While this isn’t necessarily true for all manufacturers or all aftermarket parts, it’s certainly worth thinking about, as you can see in this post from Autotrader.

It’s also worth knowing that the parts themselves won’t be guaranteed, unlike genuine parts which usually have a warranty of at least a year.
