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.

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 X15 engine relies on a carefully designed emissions system to meet modern environmental standards. One important component in this system is the DOC filter (Diesel Oxidation Catalyst), OEM 5417561, used in many 2018–2021 Cummins X15 applications. This component helps manage exhaust gases before they move further through the aftertreatment system.
Located within the exhaust assembly, the DOC filter begins the process of converting harmful exhaust compounds into less harmful emissions. By using a catalytic reaction, it helps treat pollutants produced during normal engine operation.
The Cummins X15 DOC filter 5417561 plays several key roles within the emissions system:
- Oxidizes hydrocarbons (HC)
- found in diesel exhaust
- Converts carbon monoxide (CO)
- into less harmful carbon dioxide
- Supports proper operation of downstream components
- such as the DPF system
- Helps meet EPA emissions requirements
- for heavy-duty diesel engines
- Maintains proper exhaust gas flow
- within the aftertreatment assembly
Because the DOC filter is positioned at the beginning of the aftertreatment process, its condition can influence how efficiently the entire emissions system operates. A functioning DOC helps ensure that exhaust gases are properly treated before reaching other filtration components.
For trucks equipped with Cummins X15 engines from 2018 to 2021, using the correct OEM part number—5417561—ensures compatibility with the original emissions system design and maintains proper exhaust treatment throughout the vehicle’s operation.
A Diesel Oxidation Catalyst (DOC) filter plays a key role in reducing harmful emissions from diesel engines. When it fails, drivers may notice warning lights, reduced engine efficiency, or increased exhaust issues. Understanding what leads to DOC filter failure can help prevent costly repairs and keep your vehicle running smoothly.
One of the most common causes is contamination inside the exhaust system. Over time, certain materials can build up on the catalyst surface and prevent it from doing its job properly.
Several factors can contribute to DOC filter failure, including:
- Excessive soot buildup
- caused by incomplete combustion
- Oil contamination
- entering the exhaust stream
- Fuel quality issues,
- such as high sulfur content
- Engine problems
- that allow unburned fuel into the exhaust
- Coolant leaks
- that introduce harmful deposits
Driving conditions can also play a role. Frequent short trips may prevent the exhaust system from reaching temperatures needed to burn off soot deposits. As a result, residue accumulates inside the DOC filter and gradually restricts exhaust flow.
Regular maintenance is one of the best ways to avoid DOC filter problems. Addressing engine issues early, using quality fuel, and ensuring proper operating conditions can help extend the life of the DOC filter and keep the emissions system functioning as intended.
The Cummins X15 DOC Filter OEM 5417561 helps reduce diesel exhaust emissions by oxidizing pollutants before they move through the aftertreatment system.
The DOC filter converts harmful exhaust gases such as carbon monoxide and hydrocarbons into less harmful compounds.
The DOC filter is installed within the exhaust aftertreatment assembly, typically positioned before the diesel particulate filter.
OEM 5417561 helps maintain proper emissions control so the vehicle meets required environmental regulations.
