SHIPPING POLICY

Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. 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.


Designed for compatibility with 2018–2021 Cummins X15 engines, the Cummins X15 DOC Filter (OEM 5417990) serves as a critical component within the diesel exhaust aftertreatment system. This Diesel Oxidation Catalyst (DOC) filter assists in reducing harmful exhaust gases by promoting the oxidation of hydrocarbons and carbon monoxide. Built to meet original equipment specifications, it provides proper fitment and dependable integration with the vehicle’s exhaust system. The construction is intended to handle the high temperatures and demanding operating environments common in heavy-duty diesel applications. Replacing a clogged or worn DOC filter with the OEM 5417990 helps maintain proper exhaust flow and supports compliance with emissions regulations.

The Cummins X15 DOC Filter (Diesel Oxidation Catalyst), OEM 5417990, is a key component within the exhaust aftertreatment system used in many 2018–2021 Cummins X15 engines. Its main function is to begin the emissions treatment process by converting certain harmful gases in diesel exhaust into less harmful compounds.

Positioned near the beginning of the exhaust system, the DOC filter works through a catalytic chemical reaction. As exhaust gases pass through the filter’s coated honeycomb structure, the catalyst reacts with specific pollutants and changes their chemical composition.

How the Cummins X15 DOC Filter Works

  • Exhaust gases enter the DOC unit
    • Exhaust produced by the engine flows into the DOC housing as it leaves the engine.
  • Catalytic materials trigger chemical reactions
    • The catalyst coating inside the filter reacts with hydrocarbons and carbon monoxide in the exhaust stream.
  • Harmful gases are converted
    • These reactions convert hydrocarbons and carbon monoxide into carbon dioxide and water vapor.
  • Heat is generated during the process
    • The oxidation process naturally increases exhaust temperatures, which helps prepare gases for the next stage of the aftertreatment system.
  • Exhaust continues to downstream components
    • After passing through the DOC, the treated exhaust moves on to components such as the Diesel Particulate Filter (DPF) and the SCR system.

Why the DOC Filter Matters

Because it handles the first stage of exhaust treatment, the Cummins X15 DOC Filter 5417990 helps ensure that downstream components operate under the right conditions. Its role in converting pollutants and managing exhaust chemistry makes it an important part of the overall emissions system for Cummins X15 engines.

A Diesel Oxidation Catalyst (DOC) filter is designed to last for many miles, but like other emissions components, it can eventually wear out or become contaminated. Whether a DOC filter can be serviced or repaired depends largely on the type of damage or buildup inside the unit.

In some cases, a DOC filter may be cleaned or serviced if the issue is related to soot or residue buildup. Professional cleaning processes can sometimes remove deposits that restrict exhaust flow and interfere with the catalyst’s function.

However, not every DOC filter problem can be fixed through service. Replacement may be necessary if the internal catalyst material has been damaged or contaminated beyond recovery.

Situations where service may be possible include:

  • Soot accumulation
    • that can be removed through professional cleaning
  • Minor residue buildup
    • from fuel or oil deposits
  • Restricted exhaust flow
    • caused by normal operational buildup

Replacement is typically required when:

  • The catalyst material becomes contaminated
    • with coolant or heavy oil deposits
  • The internal structure is cracked or melted
    • from excessive heat
  • The catalyst coating has deteriorated
    • and can no longer treat exhaust gases

A proper inspection and diagnostic scan can help determine the best course of action. Identifying the root cause of the issue is important, since underlying engine problems can lead to repeated DOC filter failures if left unresolved.

The DOC filter is installed in the exhaust aftertreatment assembly before the diesel particulate filter.

The diesel oxidation catalyst converts certain exhaust gases into less harmful compounds before they move through the rest of the emissions system.

Yes, OEM 5417990 is manufactured to match the specifications of the original DOC filter used in compatible Cummins X15 applications.

The filter contains a catalyst-coated substrate housed inside a metal casing designed for diesel exhaust systems.
