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.


Supporting proper exhaust aftertreatment operation, the Cummins X15 DOC Filter 2018–2021 (OEM 5417993) is designed for compatibility with select Cummins X15 diesel engines. This Diesel Oxidation Catalyst (DOC) filter helps reduce harmful exhaust gases by facilitating the oxidation of hydrocarbons and carbon monoxide within the exhaust stream. Built to meet original equipment specifications, it offers reliable fitment and integration with the existing emissions system. The unit is constructed with durable materials to withstand the high temperatures and demanding conditions commonly found in heavy-duty diesel applications. Replacing a worn or restricted DOC filter with the OEM 5417993 helps maintain proper exhaust flow and supports compliance with emissions standards.

The Cummins X15 DOC Filter (Diesel Oxidation Catalyst), OEM 5417993, is a key component in the emissions system used in many heavy-duty trucks between 2018 and 2021. It is responsible for beginning the treatment of exhaust gases as they leave the engine, helping reduce harmful pollutants before they continue through the rest of the aftertreatment system.

Positioned early in the exhaust flow, the DOC filter uses a catalytic surface that reacts with specific gases found in diesel exhaust. This reaction converts certain harmful compounds into less harmful substances, preparing the exhaust for additional treatment by downstream components.

Key Reasons the Cummins X15 DOC Filter Is Important

  • Reduces harmful exhaust gases
    • such as hydrocarbons and carbon monoxide
  • Supports the proper operation of the Diesel Particulate Filter (DPF)
  • Helps trucks meet emissions regulations
    • for heavy-duty diesel engines
  • Stabilizes exhaust temperatures
    • within the aftertreatment system
  • Maintains consistent exhaust flow
    • throughout the emissions system

Because it performs the first stage of exhaust treatment, the DOC filter influences how efficiently other components in the aftertreatment system function. If the DOC is not operating correctly, it can affect the entire emissions process.

For trucks equipped with Cummins X15 engines from 2018 to 2021, using the correct component—OEM 5417993—helps maintain proper emissions control and supports the reliability of the exhaust aftertreatment system.

A Diesel Oxidation Catalyst (DOC) filter is designed to last for many miles, but it will eventually require replacement as deposits accumulate and the catalyst material ages. The replacement interval can vary depending on driving conditions, fuel quality, and how well the engine is maintained.

In many diesel applications, a DOC filter may last 200,000 to 400,000 miles before replacement becomes necessary. However, heavy-duty use, poor maintenance, or contamination in the exhaust system can shorten that lifespan.

Several factors can affect how long a DOC filter lasts, including:

  • Frequent short trips 
    • that prevent the exhaust system from reaching proper temperature
  • Poor fuel quality
    • that leaves deposits on the catalyst surface
  • Engine issues
    • that allow unburned fuel into the exhaust
  • Oil contamination
    • entering the exhaust stream
  • Excessive soot buildup
    • over time

Drivers should also watch for signs that the DOC filter may be nearing the end of its service life. Warning lights, diagnostic trouble codes, and increased exhaust restrictions may all indicate a problem.

Routine inspections of the emissions system can help identify buildup or contamination early. Addressing engine problems promptly and maintaining proper operating conditions can help extend the life of the DOC filter and reduce the likelihood of premature replacement.

The DOC filter helps convert certain exhaust gases before they move through the rest of the emissions system.

Heavy-duty commercial trucks equipped with Cummins X15 engines between 2018 and 2021 may use this filter.

Compatibility can be confirmed by matching OEM number 5417993 with the engine model and production year.

Exhaust gases pass through a catalyst-coated substrate that assists with chemical conversion.
