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.

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 compatibility with 2018–2022 Cummins X12 and X15 engines, the Cummins X12, X15 SCR Filter (OEM 5418386) is a vital component of the diesel exhaust aftertreatment system. This Selective Catalytic Reduction (SCR) filter works with diesel exhaust fluid (DEF) to convert nitrogen oxides in the exhaust stream into less harmful gases before they exit the vehicle. Manufactured to meet original equipment specifications, it is designed for proper fitment and dependable integration with existing emissions components. The durable construction is built to withstand high temperatures and demanding operating conditions commonly found in heavy-duty diesel applications. Replacing a worn or restricted SCR filter with the OEM 5418386 helps maintain proper exhaust aftertreatment function and supports compliance with emissions regulations.

The Cummins X12, X15 SCR Filter (Selective Catalytic Reduction), OEM 5418386, is a key component in the exhaust aftertreatment system. It is designed to reduce nitrogen oxide (NOx) emissions by using a chemical reaction that transforms harmful gases into less harmful compounds before they exit the exhaust.

This SCR filter operates after exhaust gases have already passed through earlier components like the Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF), making it one of the final stages in the emissions process.

How the Cummins SCR Filter Works

  • Exhaust gases enter the SCR system
    • After initial treatment, exhaust flows into the SCR filter containing the catalyst material.
  • Diesel Exhaust Fluid (DEF) is injected
    • DEF is sprayed into the exhaust stream before it reaches the SCR catalyst.
  • DEF breaks down into ammonia
    • Heat in the exhaust converts DEF into ammonia, which is necessary for the reaction.
  • Chemical reaction occurs inside the catalyst
    • The ammonia reacts with nitrogen oxide (NOx) gases within the SCR filter.
  • NOx is converted into safer compounds
    • This reaction transforms NOx into nitrogen and water vapor.
  • Cleaned exhaust exits the system
    • After the reaction, the treated exhaust gases leave the system with reduced harmful emissions.

The Cummins X12, X15 SCR Filter OEM 5418386 plays a critical role in reducing NOx emissions and ensuring the engine meets modern emissions standards. By completing the final stage of exhaust treatment, it helps maintain proper system function and supports cleaner exhaust output.

A Selective Catalytic Reduction (SCR) filter is designed for long-term use as part of a diesel vehicle’s emissions system. It works with diesel exhaust fluid (DEF) to reduce nitrogen oxide emissions, and under normal conditions, it does not require frequent replacement.

In many applications, an SCR filter can last 300,000 to 500,000 miles or more. However, the actual lifespan depends on how the vehicle is used and how well the emissions system is maintained.

Several factors can affect how often an SCR filter needs replacement, including:

  • Contaminated or poor-quality DEF
    • that leaves deposits in the system
  • DEF crystallization
    • that interferes with proper operation
  • Faulty sensors or injectors
    • affecting DEF dosing
  • Excessive soot or residue
    • entering the exhaust system
  • Unresolved engine issues
    • that impact emissions components

Unlike a DPF, an SCR filter does not typically require regular cleaning cycles. However, it can become contaminated over time, which reduces its ability to treat exhaust gases effectively.

Drivers should watch for warning signs such as emissions-related fault codes, DEF system alerts, or restricted vehicle operation. These may indicate that the SCR filter is no longer functioning properly.

Routine maintenance and proper DEF handling can help extend the lifespan of the SCR filter and reduce the likelihood of premature replacement.

The system converts nitrogen oxides into nitrogen and water through catalytic reactions in the exhaust stream.

Diesel exhaust fluid is injected into the exhaust to react within the SCR module and reduce emissions.

The component is located within the aftertreatment assembly along the exhaust system downstream of other emissions components.

The unit contains a catalyst-coated substrate that facilitates chemical reactions as exhaust gases pass through.
