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.
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.
Engineered for select Cummins X15 engines from 2018–2021, the Cummins X15 DOC Filter, OEM Part Number 5417992, helps convert harmful exhaust gases into less harmful emissions before they pass through the rest of the aftertreatment system. Built to meet OEM specifications, it delivers precise fitment and durable construction suited for demanding on-road and vocational environments. When a DOC filter becomes restricted or fails, it can trigger warning indicators, increased exhaust backpressure, or other aftertreatment concerns that require attention. Timely replacement supports consistent emissions system function and helps maintain overall engine reliability. Tamerx Diesel Products LLC supplies trusted diesel components designed to keep your Cummins X15 engine operating cleanly and reliably.

Effective emissions control begins at the front of the aftertreatment system, and the Cummins X15 DOC Filter OEM 5417992 plays a vital role in that process. Designed for 2018–2021 Cummins X15 engines, this Diesel Oxidation Catalyst (DOC) helps treat exhaust gases before they move downstream to the DPF and SCR systems.
The primary role of the DOC filter is to reduce harmful exhaust gases through oxidation reactions.
The Cummins X15 DOC Filter OEM 5417992 is responsible for:
- Converting carbon monoxide into carbon dioxide
- Oxidizing unburned hydrocarbons into water vapor and carbon dioxide
- Reducing exhaust odor
- Generating heat to support DPF regeneration
- Assisting with overall emissions compliance
Inside the DOC is a honeycomb-style substrate coated with catalyst materials. As hot exhaust gases pass through, chemical reactions occur on the catalyst surface, transforming specific pollutants into less harmful compounds.
An important secondary function of the DOC is heat generation. The oxidation process increases exhaust temperature, which helps the Diesel Particulate Filter reach the temperatures needed to burn off accumulated soot during regeneration.
The OEM 5417992 DOC filter is engineered specifically for Cummins X15 applications, ensuring proper fitment and compatibility with factory aftertreatment components.
When functioning correctly, it supports cleaner exhaust output, efficient downstream emissions performance, and dependable engine operation.
The DOC (Diesel Oxidation Catalyst) filter helps convert harmful exhaust gases into less harmful emissions before they pass through the rest of the aftertreatment system. When it begins to fail, warning lights and exhaust-related symptoms often appear.
One of the most common signs is an illuminated check engine or aftertreatment warning light.
Other symptoms of a bad DOC filter include:
- Catalyst efficiency fault codes
- Failed emissions testing
- Strong or unusual exhaust odor
- Increased exhaust temperatures
- Excessive exhaust restriction
- Rattling noise from inside the exhaust housing
Internal contamination is a frequent cause of DOC problems. Oil or coolant entering the exhaust system can coat the catalyst surface and reduce its effectiveness.
Overheating can also damage the internal substrate. If the catalyst structure cracks or melts, exhaust flow may become restricted and affect engine operation.
In some cases, faulty temperature or pressure sensors can mimic DOC failure. Proper diagnostics are essential to confirm whether the issue lies within the DOC filter or another related component.
Addressing the problem early helps protect the entire aftertreatment system and prevent more costly repairs.
The Cummins 5417992 DOC Filter oxidizes hydrocarbons and carbon monoxide in exhaust gases as part of the engine’s emissions control system.
This DOC Filter is installed in the beginning section of the exhaust aftertreatment system before gases reach downstream components.
Yes — the Cummins 5417992 DOC Filter is manufactured to meet original equipment specifications for direct fitment.
It helps convert harmful exhaust hydrocarbons and carbon monoxide into less harmful substances early in the aftertreatment sequence.
