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.
Covering 2011–2013 Cummins ISX15 applications, the SCR filter with OEM 4329094 plays a vital role in the diesel exhaust aftertreatment system. This selective catalytic reduction filter is engineered to fit the ISX15 engine’s exhaust configuration and emissions sensor locations, ensuring proper integration with factory DEF (diesel exhaust fluid) delivery and control systems. Its function is to work with DEF to reduce nitrogen oxide (NOₓ) emissions in the exhaust stream, helping these vehicles meet applicable emissions requirements for the listed model years. Reliable SCR filter operation supports consistent exhaust flow and contributes to the proper function of downstream aftertreatment components. This page provides application-specific details to assist with identifying the Cummins ISX15 SCR Filter 2011–2013 (OEM 4329094) for service and replacement needs.

What Is the Cummins ISX15 SCR Filter (2011–2013, OEM 4329094)?
The Cummins ISX15 SCR Filter, OEM 4329094, is a key component in the Selective Catalytic Reduction (SCR) emissions system used on Cummins ISX15 diesel engines from 2011 through 2013. Its role is to work with Diesel Exhaust Fluid (DEF) and other aftertreatment parts to help treat exhaust gases before they leave the vehicle.
Unlike traditional filters that trap soot, this SCR filter is part of a chemical system that promotes reactions to reduce harmful nitrogen oxides (NOx). As exhaust flows through the filter assembly, DEF is metered into the exhaust stream by the dosing system and activated by heat. Inside the SCR filter, catalysts encourage the conversion of NOx into nitrogen and water vapor, which are far less harmful to the environment.
This component fits into the aftertreatment system downstream of the diesel oxidation catalyst (DOC) and diesel particulate filter (DPF). Together with sensors and the DEF dosing module, it helps the engine meet emissions regulations for NOx output.
In everyday operation, the OEM 4329094 SCR filter:
- Receives treated exhaust after DOC/DPF stages
- Works with DEF dosing to facilitate chemical conversion
- Helps maintain regulated emissions output
- Interfaces with sensors for proper system control
The Cummins ISX15 SCR filter OEM 4329094 plays a central role in the engine’s emissions control system by supporting NOx reduction in 2011–2013 applications.
You can prolong the lifespan of an SCR filter (SCR catalyst) by protecting it from DEF contamination, preventing crystallization, and keeping exhaust temperatures and dosing components operating correctly. Since the SCR relies on chemical reactions to reduce NOx, the goal is to keep the catalyst surface clean and functioning.
Here are the best ways to extend SCR filter lifespan:
- Use only high-quality DEF
- Always use DEF that meets ISO standards and comes from sealed, reputable containers. Poor-quality DEF introduces minerals and contaminants that permanently poison the catalyst.
- Prevent DEF contamination
- Never mix DEF with water, fuel, or additives. Even small amounts of contamination can damage the SCR and trigger NOx efficiency faults.
- Store DEF properly
- Keep DEF in a cool, clean environment and sealed tightly. Heat and dirt can degrade DEF quality and increase the risk of deposits.
- Avoid DEF crystallization
- Crystals form when DEF dries in the doser/injector or exhaust pipe. Make sure the system heats correctly and dosing components aren’t leaking or dripping.
- Fix DEF dosing issues early
- A weak DEF pump, faulty injector, clogged doser, or damaged lines can cause under- or over-dosing, which accelerates SCR failure.
- Maintain proper exhaust temperatures
- Frequent short trips can keep the exhaust too cool, preventing proper chemical conversion and increasing deposit buildup. Regular steady driving helps maintain correct operating conditions.
- Keep upstream components healthy
- A failing DOC or DPF can affect exhaust flow and temperature, placing extra strain on the SCR and causing premature catalyst degradation.
An SCR lasts longest when DEF quality is protected, dosing remains accurate, crystallization is prevented, and upstream emissions components are functioning properly.
It is essential to the SCR system, which helps control regulated exhaust emissions.
A clogged filter can cause restriction in the exhaust and trigger aftertreatment warnings.
NOx sensors measure emissions before and after the filter to ensure effective conversion.
Yes, it is an original Cummins part for the ISX15 SCR system from 2011–2013.
