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.

When it comes to replacing the Cummins B6.7 / L9 DPF Filter (OEM 5579369), confirming compatibility is an important step that goes beyond just matching the part name. While this filter is widely used, making sure it fits your exact engine setup will help you avoid installation issues and costly downtime.
This particular DPF is primarily designed for Cummins ISB / B6.7 engines, especially EPA17 configurations, making it a common fit for many 2018–2023 applications. However, not every engine within that range uses the same configuration, so verification is still necessary.
To ensure compatibility, here are the key steps you should follow:
- Confirm your engine model and emissions setup
- This DPF is typically used on ISB 6.7L (B6.7) engines, so verifying your exact engine model is the first step.
- Use your Engine Serial Number (ESN)
- The ESN provides the most accurate way to match parts. It identifies your engine’s exact build and ensures the filter is correct for your configuration.
- Check the OEM part number on your current DPF
- If your existing filter shows 5579369 (or cross-references like 5579369RX), it’s a direct replacement.
- Verify cross-reference part numbers
- This DPF may also match other interchangeable numbers (e.g., 4394227 series), which can help confirm fitment.
- Consult a Cummins dealer or parts specialist
- Providing your ESN or VIN allows professionals to confirm compatibility using official databases.
In short, even if your engine is labeled B6.7 or L9 within the correct year range, the most reliable way to confirm fitment is by using your ESN and part number match. This ensures the DPF installs correctly and functions exactly as intended within your emissions system.
A Diesel Particulate Filter (DPF) is designed to trap and burn off soot, but its lifespan depends heavily on how the vehicle is driven and maintained. Without proper care, soot and ash can build up faster than the system can handle.
The best way to extend the life of a DPF filter is to ensure it can regularly complete its regeneration process and operate under the right conditions.
Here are key ways to help your DPF filter last longer:
- Drive at sustained speeds when possible
- Highway driving allows the exhaust system to reach the temperature needed to burn off soot effectively. Short trips can prevent proper regeneration.
- Avoid excessive idling
- Long idle times reduce exhaust temperature, leading to faster soot accumulation inside the filter.
- Use high-quality fuel and proper oil
- Clean fuel and the correct low-ash engine oil help minimize the amount of residue entering the DPF.
- Pay attention to regeneration cycles
- If your vehicle is actively regenerating, avoid shutting it off mid-cycle, as this can leave unburned soot in the filter.
- Address engine issues promptly
- Problems like faulty injectors or poor combustion can increase soot production and overload the DPF.
- Schedule routine inspections
- Regular checks can catch early signs of buildup or sensor issues before they lead to more serious problems.
By maintaining proper driving habits and staying on top of maintenance, you can significantly extend the lifespan of your DPF filter and keep your emissions system working efficiently.
It works alongside the DOC and SCR systems to reduce particulate emissions, forming a critical part of the multi-stage aftertreatment process.
Restricted flow can increase backpressure in the exhaust system, which may affect engine operation and trigger system alerts.
Yes, it is engineered to handle continuous high exhaust flow and temperature conditions typical of commercial trucks and vocational equipment.
Correct installation ensures proper sealing, accurate sensor readings, and consistent exhaust flow, all of which are critical for the aftertreatment system to function correctly.
