Is there a difference between OEM and aftermarket NOx sensors for Detroit DD15 engines?

When it comes to NOx sensors for Detroit DD15 engines, there can be a significant difference between OEM and aftermarket options. OEM sensors, or original equipment manufacturer sensors, are manufactured by the same company that built your engine. These sensors are designed specifically for your engine and typically meet the highest standards for quality and performance. However, OEM sensors can be quite expensive and may not always be readily available.

On the other hand, aftermarket NOx sensors are manufactured by third-party companies and may not always meet the same quality standards as OEM sensors. This can lead to issues with performance and longevity.

At FleetRun, we understand the importance of high-quality, reliable NOx sensors for your Detroit DD15 engine. That's why we offer an aftermarket NOx sensor that is designed to meet or exceed OEM standards. Our NOx sensors are rigorously tested to ensure they meet the highest standards for performance and longevity. And unlike OEM sensors, our aftermarket sensors come at a reasonable price, so you can save money without sacrificing quality. Furthermore, we offer after-sale support and deliver the parts to the customer's door for a convenient experience. So, when you choose FleetRun, you can rest assured that you are getting a quality product at an affordable price, and with excellent support.
