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.

The SCR (Selective Catalytic Reduction) filter is a key component in diesel aftertreatment systems, designed to handle the final stage of emissions control. In Paccar MX13 engines, this filter works with Diesel Exhaust Fluid (DEF) to convert nitrogen oxide (NOx) emissions into nitrogen and water vapor. This process helps reduce harmful exhaust output and supports proper system operation across heavy-duty applications.

  • Reduces NOx Emissions at the Final Stage
    Positioned toward the end of the exhaust system, the SCR filter targets nitrogen oxides that remain after earlier filtration processes, completing the emissions treatment cycle.
  • Works with DEF for Chemical Conversion
    DEF is injected into the exhaust stream and reacts within the SCR catalyst, transforming harmful gases into less harmful compounds before they exit the tailpipe.
  • Supports a Multi-Stage Aftertreatment System
    The SCR filter works alongside components like the DOC and DPF, each handling different types of emissions to ensure balanced and efficient exhaust processing.
  • Designed for Paccar MX13 Engines (2013–2017)
    Built to OEM 1981227 specifications, this unit is engineered for compatibility with MX13 engines, ensuring proper fitment within the factory aftertreatment system.
  • Built for Heavy-Duty Diesel Operation
    Operating in high-temperature exhaust environments, the SCR filter is constructed to handle continuous use and demanding workloads common in commercial vehicles.

The SCR filter plays a critical role in maintaining emissions control and system efficiency. For Paccar MX13 engines, having the correct SCR unit in place helps ensure consistent NOx reduction, supports overall aftertreatment performance, and keeps the system operating reliably over time.

Keeping an SCR filter in good condition requires consistent care of both the emissions system and the engine itself. Since the SCR relies on proper DEF dosing and clean exhaust flow to function efficiently, routine maintenance plays a major role in extending its lifespan and preventing costly failures.

  • Use only high-quality, manufacturer-approved Diesel Exhaust Fluid (DEF) to avoid contamination and internal deposits.
  • Store DEF properly in sealed containers to prevent exposure to dirt, moisture, or extreme temperatures.
  • Regularly inspect the DEF injector for crystallization buildup that can affect spray patterns and dosing.
  • Address engine issues such as oil consumption or coolant leaks promptly to prevent contamination of the SCR catalyst.
  • Ensure the Diesel Particulate Filter (DPF) is functioning correctly, as upstream problems can impact SCR performance.
  • Monitor warning lights and fault codes, and diagnose issues early before they lead to long-term damage.
  • Avoid excessive idling or frequent short trips that prevent the exhaust system from reaching optimal operating temperatures.
  • Follow scheduled maintenance intervals to check sensors, wiring, and related emissions components.

Proper maintenance and early problem detection are key to extending the life of an SCR filter. By keeping the system clean and operating under the right conditions, you can maintain reliable emissions control and avoid unnecessary repairs.
