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 to support emissions compliance, the Paccar MX13 SCR Filter 2022–2024, OEM Part Number 2254599, is designed for use with select MX13 engine applications. This selective catalytic reduction (SCR) filter works within the aftertreatment system to help reduce NOx emissions through controlled DEF interaction. Built to meet OEM specifications, it ensures accurate fitment and durable construction suited for demanding on-road environments. When an SCR filter becomes restricted or fails, it can trigger warning lights, increase regeneration frequency, or lead to exhaust system concerns, making timely replacement important. Tamerx Diesel Products LLC supplies trusted diesel aftertreatment components to help keep your Paccar MX13 engine operating cleanly and reliably.

The Paccar MX13 SCR Filter OEM 2254599 is a core component of the Selective Catalytic Reduction (SCR) system used on MX13 engines from 2022 through 2024. The SCR filter works with Diesel Exhaust Fluid (DEF) to convert harmful nitrogen oxide (NOx) emissions into nitrogen and water vapor. While the unit appears as a single assembly, it contains several internal and external elements that allow it to perform this chemical conversion efficiently.
Primary SCR Filter Components
- SCR Housing
- A robust metal casing that encloses and protects the internal catalyst structure while providing connection points for exhaust piping.
- Catalyst Substrate
- A honeycomb-style core made of ceramic or metallic material with thousands of tiny channels. This substrate provides an extensive surface area where chemical reactions occur.
- Catalyst Coating
- Precious metals (such as vanadium, tungsten, or zeolites) applied to the substrate surface. These materials act as catalysts to accelerate chemical reactions between ammonia (from DEF) and NOx.
- Inlet Cone / Outlet Cone
- Internal components that guide exhaust gases smoothly into and out of the catalyst substrate.
Supporting & Sealing Elements
- Gaskets and Seals
- Heat-resistant seals that prevent exhaust leaks where the SCR filter connects to other exhaust components.
- Mounting Flanges
- Machined connection surfaces that secure the SCR filter to adjacent exhaust components with bolts or clamps.
Sensor & Monitoring Interfaces (When Equipped)
Some SCR systems include ports or mounts for sensors, such as:
- Temperature Sensor Ports
- Allow temperature probes to monitor exhaust heat for control and diagnostics.
- Pressure Sensor Ports
- Can be used in advanced systems to monitor exhaust flow or backpressure across the SCR filter.
How These Components Work Together
When DEF is injected upstream into the exhaust stream, it decomposes into ammonia. As exhaust gases enter the SCR housing, they flow through the catalyst substrate. The ammonia then reacts with NOx on the catalyst surface, converting it into nitrogen and water vapor. The precious metal coating facilitates these reactions at lower temperatures.
The housing, gaskets, and flanges ensure that the unit is sealed and properly integrated into the exhaust system, while sensor ports enable monitoring of operating conditions.
Together, these components allow the Paccar MX13 SCR Filter OEM 2254599 to reduce NOx emissions, support emissions compliance, and maintain stable exhaust flow in 2022–2024 MX13 applications.
The SCR (Selective Catalytic Reduction) filter works with Diesel Exhaust Fluid to reduce NOx emissions in your exhaust system. While it is designed for long-term use, it will eventually require replacement based on condition rather than mileage.
You should replace your SCR filter when diagnostics confirm it can no longer convert emissions efficiently.
Common signs it may be time for replacement include:
- Persistent NOx efficiency fault codes
- Ongoing SCR or check engine warning light
- Failed emissions testing
- Reduced engine operation or speed limitation
- Excessive DEF consumption
- Confirmed internal substrate damage
In some cases, contamination from poor-quality DEF or engine issues can coat the catalyst surface and reduce efficiency. Minor buildup may be addressed early, but once the internal structure is damaged, replacement is typically required.
Prolonged overheating or severe contamination can crack or melt the catalyst substrate, making cleaning ineffective.
Before replacing the SCR filter, a professional inspection is essential. A technician will review NOx sensor data, inspect dosing performance, and check for related engine or exhaust problems.
Replacing a failing SCR filter promptly helps protect the rest of the aftertreatment system and maintain proper emissions control.
Yes, a failing or restricted SCR Filter can trigger emissions system diagnostic codes and affect aftertreatment readings.
