We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Tamerx Diesel Products only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.
The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.
Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.
Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".
If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.
As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.
What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.
"This Product Doesn't Have a Core"
Accurate emissions monitoring starts with the Cummins QSB 6.7L NOx Sensor 2018–2024 (OEM 4326869). Designed for Cummins QSB 6.7L engines, this sensor measures nitrogen oxide levels within the exhaust system to support proper aftertreatment function. Manufactured to meet OEM specifications, it provides reliable fitment and consistent communication with the engine control system. Using the correct NOx sensor helps maintain steady emissions system operation and dependable performance.

Accurate emissions monitoring is essential for keeping diesel engines running within regulated limits. The NOx (nitrogen oxide) sensor is a critical component in the aftertreatment system, designed to measure the level of NOx gases in the exhaust stream. In Cummins QSB 6.7L engines, this sensor provides real-time feedback to the engine control module (ECM), allowing the system to adjust Diesel Exhaust Fluid (DEF) dosing and maintain proper emissions control.
- Measures NOx Levels in the Exhaust Stream
The sensor detects the concentration of nitrogen oxides in the exhaust, providing essential data for monitoring emissions output. - Supports Accurate DEF Injection
The ECM relies on NOx sensor data to calculate the correct amount of DEF needed for the SCR system to convert harmful gases into nitrogen and water vapor. - Acts as a Feedback Mechanism for the SCR System
By comparing NOx levels before and after treatment, the sensor helps verify that the SCR system is functioning correctly and efficiently. - Helps Prevent Emissions System Faults
Accurate readings help avoid issues such as incorrect DEF dosing, which can lead to fault codes, reduced engine power, or increased emissions. - Designed for Cummins QSB 6.7L Engines (2018–2024)
Built to OEM 4326869 specifications, this NOx sensor is intended for proper integration with the factory emissions system, ensuring reliable communication with the ECM.
The NOx sensor plays a vital role in maintaining emissions system accuracy and overall engine operation. For Cummins QSB 6.7L engines, a properly functioning sensor helps ensure precise exhaust monitoring, supports SCR performance, and keeps the aftertreatment system working as intended.
It specifically measures nitrogen oxides such as NO and NO₂ in the exhaust.
It provides data that allows the system to adjust DEF dosing and reduce harmful gases.
Yes, it continuously monitors exhaust gas levels while the system is running.
The system may not properly control emissions and could trigger warning lights or reduced performance.
