5 Reasons to Buy OEM Oxygen Sensors Instead of Aftermarket
Are you searching for a replacement oxygen sensor? You've probably notice that there’s a large selection of aftermarket oxygen sensors available for your Nissan. Should you consider getting one of these instead of an OEM oxygen sensor?
Our answer is a resounding no. An OEM oxygen sensor is a much safer bet than an aftermarket oxygen sensor for the reasons listed below. First, let’s briefly go over what OEM and aftermarket parts are.
A Quick Overview of OEM and Aftermarket Parts
- OEM automobile parts: OEM stands for Original Equipment Manufacturer. This means OEM auto parts are made by either the vehicle manufacturer or its subcontractor. If you choose a Nissan OEM sensor, you’re using a part that’s produced with the exact same materials and fitment as the stock part, by the same manufacturer.
- Aftermarket auto parts: These are non-OEM parts produced by private companies. The companies are not vendors for Nissan. These manufacturers are not held to Nissan's strict standards, so their parts vary in quality and reliability.
We always recommend buying OEM parts instead of aftermarket parts. They are a safer bet. But, we strongly recommend it to anyone looking for a replacement oxygen sensor. These sensors serve an important role in ensuring the smooth operation of your engine. You really shouldn’t skimp on quality when it comes to oxygen sensors.
So why do OEM oxygen sensors surpass aftermarket oxygen sensors? Five reasons:
1. Guaranteed Quality
It’s not uncommon for aftermarket parts to be fabricated with inferior materials just so the manufacturers could save a few bucks. There are some well-built aftermarket oxygen sensors. But, there’s still no guarantee that they’ll work with the same level of precision as an OEM oxygen sensor. The bottom line: you don’t know what you’re getting with an aftermarket sensor.
With OEM oxygen sensors, you know exactly what you’re getting: a high-quality sensor specifically designed to work with your Nissan engine. Nissan builds their oxygen sensors to last. They make a point to use top quality materials and, of course, design their sensors to work optimally with Nissan engines.
2. Precise Fitment

Many aftermarket oxygen sensors are “universal fit”. Cutting, splicing and soldering the wiring harness is often required to install an aftermarket oxygen sensor. This increases the risk of problems due to the splice failing. Also, if you cut off the old connector and splice on the sensor, it's difficult to go back to an OEM sensor.
Aftermarket sensors are okay in the sense that they’re programmed to work with Nissan ECUs. But there’s no telling that they come with the right connectors or are made of sturdy enough materials to withstand constant exposure to hot exhaust.
Nissan oxygen sensors come with the correct connectors to make installation easy. Each OEM sensor is designed specifically to work with the engine it’s meant to be paired with.
3. Instant Accessibility
OEM parts are incredibly easy to find. All you have to do is to either:
- Visit a Nissan dealership and request a replacement oxygen sensor for your vehicle.
- Go online and do a search on your Nissan's year and model to find the right oxygen sensor that’s designed specifically for your vehicle.
It’s not that easy to find a good aftermarket oxygen sensor for your vehicle. You have to do tons of research beforehand to ensure that you’re selecting a good brand. Then you have to make sure that the aftermarket oxygen sensor that’s on top of your list will work with your specific Nissan.
4. Comprehensive Warranty Coverage
All Nissan OEM parts, including those sold online at Nissan Parts Plus, are covered by Nissan’s Limited Warranty. The warranty is good for 12 months or 12,000 miles. Any Nissan dealer will honor the warranty should your OEM sensor have any issues within the coverage period. You can’t say the same about aftermarket oxygen sensors.
Buying an aftermarket oxygen sensor is a huge gamble for several reasons:
- Many aftermarket parts come with no warranty.
- The aftermarket parts that do come with a warranty are typically returnable only at the place where you bought them.
Nissan’s oxygen sensors are built to last. Aftermarket oxygen sensors? Not so much. Many car owners can attest that aftermarket oxygen sensors rarely last as long as OEM oxygen sensors.
