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.
The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

The Cummins ISX15 SCR Outlet Catalyst Module (OEM 4329017) is an important part of the engine’s exhaust aftertreatment system. Its main responsibility is to reduce nitrogen oxide (NOx) emissions before exhaust gases leave the vehicle. OEM 4329017 is identified as an SCR catalyst for Cummins ISX applications and is also associated with OEM 2871599.
Although this component does not directly produce engine power, its performance can affect emissions compliance and the overall operation of the aftertreatment system.
Why Is the Cummins 4329017 SCR Catalyst Important?
- Reduces harmful NOx emissions
- The SCR catalyst converts nitrogen oxides in the exhaust into primarily nitrogen and water through a catalytic reaction.
- Works with Diesel Exhaust Fluid (DEF)
- DEF is introduced upstream and ultimately provides ammonia. When exhaust reaches the SCR catalyst, ammonia reacts with NOx to support the emissions-reduction process.
- Completes a major stage of exhaust cleanup
- The SCR catalyst treats NOx after other aftertreatment processes have addressed pollutants such as soot and unburned hydrocarbons.
- Supports emissions compliance
- Effective NOx conversion is essential for maintaining the emissions performance expected from the engine and aftertreatment system.
- Works with sensors and electronic controls
- NOx and temperature sensors help the engine control system determine whether SCR operating conditions and catalyst efficiency are within the expected range.
- Helps avoid emissions-related operating issues
- Poor SCR performance can contribute to warning lights and fault codes. If an emissions problem remains unresolved, certain conditions can eventually lead to an engine derate.
An Essential Part of the Aftertreatment System
The Cummins ISX15 SCR Outlet Catalyst Module (OEM 4329017) is significant because it helps complete the engine’s NOx-reduction process. By working with DEF and the rest of the aftertreatment system, it helps maintain cleaner exhaust and dependable emissions performance.
Keeping the DEF dosing system, sensors, and upstream aftertreatment components in good condition can also help protect the SCR catalyst from unnecessary contamination and premature deterioration.
A failing SCR Outlet Catalyst Module may not cause obvious engine problems immediately. In many cases, the vehicle’s diagnostic system detects declining catalyst efficiency first. As the problem becomes more serious, you may experience warning lights, recurring fault codes, or reduced engine operation.
Here are some common signs to watch for:
- Check engine or emissions warning light
- The vehicle may illuminate a warning light when the control system detects abnormal SCR performance.
- Recurring SCR efficiency codes
- Fault codes related to low catalyst efficiency or poor NOx conversion may repeatedly return after being cleared.
- High downstream NOx readings
- If NOx levels remain higher than expected after passing through the SCR catalyst, the module may no longer be converting emissions effectively.
- Engine derate or reduced power
- An unresolved SCR fault can eventually cause some diesel engines to limit power or vehicle speed.
- Abnormal DEF consumption
- Unexpected changes in Diesel Exhaust Fluid usage may accompany an SCR system problem, although DEF consumption alone doesn't confirm catalyst failure.
- Physical or heat damage
- Cracks, severe corrosion, overheating, or damage to the internal catalyst substrate can prevent the module from operating correctly.
- Failed emissions testing
- A deteriorated catalyst may no longer reduce NOx sufficiently to meet applicable emissions requirements.
- SCR problems that remain after other repairs
- If the DEF injector, NOx sensors, temperature sensors, wiring, and exhaust system have been checked but efficiency problems continue, the catalyst module may require further testing.
These symptoms do not automatically mean the SCR Outlet Catalyst Module needs replacement. Faulty NOx sensors, incorrect DEF dosing, contaminated DEF, exhaust leaks, or engine-related problems can produce similar symptoms. A complete diagnostic inspection should confirm catalyst failure before the module is replaced.
DEF provides the ammonia required for catalytic reactions inside the 4329017-type SCR system that convert NOx into nitrogen and water.
No, 4329017 is an aftertreatment/SCR device rather than an individual NOx or temperature sensor.
Yes, the sensor ports and attachment points should be inspected because direct-fit 4329017 replacements are designed with the necessary provisions for the applicable exhaust sensors.
No, 4329017 should be matched by OEM number and engine configuration because correct SCR fitment involves more than simply matching exterior dimensions.
