When it’s time to replace a part on your Nissan, whether it’s brake pads, filters, or something more serious, you’ve got a choice to make: genuine parts or aftermarket ones. And if you’re not a mechanic or someone who spends weekends under the bonnet, the decision can be confusing.

What Are Genuine Parts?
Genuine Nissan car parts Perth, also called OEM or original equipment manufacturer parts, are made by the same company that produced your vehicle. They’re designed to match the exact specifications of your Nissan model—same fit, same function.
In most cases, these are the same parts that were in your car when it rolled off the production line. So you know they’ll fit just right, work the way they’re supposed to, and keep your vehicle running as intended.
What About Aftermarket Parts?
Aftermarket parts are made by third-party manufacturers. They’re not built by the same company that made your vehicle, but they’re designed to work in the same way. Think of them as alternatives.
Now, here’s where it gets a bit more nuanced; some aftermarket parts are incredibly high quality, while others aren’t up to scratch. The market is big, varied, and not all parts are created equal.
Pros and Cons: A Quick Look
To make it easier to see the differences, here’s a side-by-side comparison of the typical strengths and trade-offs:
Genuine Parts
- Perfect fit – Designed specifically for your Nissan model
- Reliable performance – You know what you’re getting
- Backed by warranty – Often included when installed by authorized repairers
- Higher cost – Usually more expensive than aftermarket
- Less variety – You get one version of the part, no alternatives
Aftermarket Parts
- Lower price – Often cheaper upfront
- More options – Multiple brands and performance levels to choose from
- Varied quality – Some parts are excellent, others not so much
- May not be an exact fit – Small design differences can affect compatibility
- No universal warranty – Depends on the supplier or manufacturer
What Matters Most: Fit, Function, and Safety
Here’s the thing: every part on your car plays a role. It’s not just about whether something “works” but how well it works, especially over time.
For example:
- A poorly fitting aftermarket bumper might rattle or not line up with your body panels.
- Brake pads that aren’t matched correctly could wear unevenly or affect stopping power.
- An air filter with subpar materials might reduce fuel efficiency.
So if the part is critical to safety, performance, or the core function of the vehicle (like brakes, suspension, or engine components), many experts recommend sticking with genuine parts or only top-tier aftermarket brands.
When Aftermarket Makes Sense
Now, this doesn’t mean aftermarket parts are a no-go. In fact, there are situations where they’re absolutely worth considering.
Let’s say you’re replacing a headlight bulb, a mirror glass, or a cabin air filter. These are simple items that don’t directly impact the car’s safety or complex systems. In these cases, a good-quality aftermarket option could save you money without much risk.
Also, if your Nissan is a bit older and you’re not worried about resale value or factory specs, aftermarket can be a practical, affordable solution.
What About Insurance and Warranties?
This is where it can get a bit tricky. If your car is still under warranty, using non-genuine parts could impact it, especially if the part is linked to a failure or claim. Some warranties only cover repairs if genuine parts are used, and they must be installed by a licensed technician.
Insurance can also play a role. After an accident, insurers might opt for aftermarket parts to keep repair costs down. But you can often request genuine parts if that’s your preference. It might just mean paying the difference.
It’s always worth checking the fine print of your policy and warranty documents before making a decision.
Don’t Just Focus on Price
It’s easy to lean toward the cheaper option, especially when a genuine part costs significantly more. But think about the long-term impact, not just the short-term savings.
Ask yourself:
How often do I want to replace this part?
Will the cheaper option affect performance?
Is this part something that affects safety?
Sometimes, paying more now saves you time, money, and stress later.
Advice for Choosing Aftermarket Parts
If you’re considering aftermarket, here are a few quick tips to make sure you’re getting something worthwhile:
- Do your research – Look into the brand and check for certifications
- Avoid the cheapest options – Bargain-basement parts often come with hidden costs
- Buy from trusted suppliers – Choose sellers with a track record, not just the lowest price
- Check fitment details – Make sure the part is designed for your exact make and model
If you’re unsure, get a second opinion from a trusted mechanic. They’ll usually know which aftermarket parts are solid and which to avoid.
So, Which Should You Choose?
There’s no one-size-fits-all answer here. The right choice depends on the part, your budget, how long you plan to keep your car, and your comfort level with risk.
Want peace of mind, especially for critical components? Go genuine.
Replacing something minor or cosmetic? Aftermarket is worth a look.
Happy to do some homework and weigh your options? You might find a quality aftermarket part that performs just as well.
It’s not about one being “better” across the board; it’s about making a smart, informed choice that fits your needs.
Before You Hit Buy…
Take a moment. Don’t just go for the first cheap option or assume genuine is always necessary. Look at what the part does, how important it is to your car’s operation, and whether the savings are really worth it in the long run.
