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.

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.

Diesel Particulate Filters (DPFs) are a cornerstone of modern emissions control systems, designed to trap and reduce soot and fine particulates from exhaust gases. The Cummins B6.7 / L9 DPF Filter (2018–2022, OEM 5579377RX) is built to meet original equipment specifications, delivering dependable filtration performance for Cummins B6.7 and L9 engines. Installing the correct OEM filter helps maintain engine efficiency, support emissions compliance, and promote longer component life.

This DPF filter contributes to improved emissions control and engine performance — here’s why it matters:

  • Captures Harmful Particulates – Effectively traps soot and solid particles from the exhaust stream, helping reduce environmental pollutants.

  • Supports Regeneration Processes – A properly functioning DPF helps the system burn off trapped soot during regeneration, keeping the filter performing at its best.

  • Helps Maintain Engine Efficiency – By stabilizing exhaust flow and reducing excessive backpressure, the filter supports smoother engine operation and consistent power delivery.

  • OEM-Grade Fit and Durability – As OEM 5579377RX, this DPF is engineered to match original manufacturer specifications for fit, filter media design, and long-lasting performance.

  • Prevents Exhaust-Related Issues – Replacing a clogged or worn filter helps avoid symptoms such as reduced power, increased fuel consumption, excessive smoke, and emissions system warnings.

A worn or blocked DPF can compromise both emissions performance and overall engine efficiency. The Cummins B6.7 / L9 DPF Filter (OEM 5579377RX) delivers the OEM-standard quality and filtration capability needed to keep your emissions system functioning smoothly and your engine running cleaner. For customers seeking a reliable replacement part, Tamerx offers high-quality components engineered to support long-lasting emissions control and dependable engine health.

A Diesel Particulate Filter (DPF) is designed to trap soot and reduce emissions in diesel vehicles, but its condition can directly influence fuel economy. When the DPF is operating as intended, the impact on fuel consumption is minimal. However, problems within the DPF system can lead to noticeable changes in how efficiently the engine uses fuel.

  • Increased exhaust restriction: A clogged or overloaded DPF creates backpressure in the exhaust system, forcing the engine to work harder and burn more fuel.

  • More frequent regeneration cycles: When soot buildup increases, the engine may trigger active regeneration more often, which consumes additional fuel.

  • Reduced engine efficiency: Improper exhaust flow caused by DPF issues can affect combustion efficiency and overall engine operation.

  • Dashboard warning lights or derate conditions: DPF-related faults may lead to limited engine power, which can change driving habits and indirectly affect fuel usage.

  • Driving conditions matter: Short trips and low-speed operation can prevent proper regeneration, increasing fuel consumption over time.

A DPF filter can affect fuel economy when it becomes restricted or is not regenerating correctly. Keeping up with regular maintenance, addressing warning signs early, and ensuring proper driving conditions can help support efficient DPF operation and maintain consistent fuel usage.

Using high-quality diesel fuel, replacing fuel filters on schedule, and ensuring the engine runs at optimal temperatures all help prevent premature soot buildup. Monitoring exhaust system alerts also supports long-term filter health.

Yes, if the filter becomes severely restricted or fails regeneration, the engine control system may reduce power to protect components. This safeguard helps prevent damage and alerts the operator to underlying issues.

During regeneration, accumulated soot traps are heated and burned into less harmful ash. This process restores filter capacity and is essential to maintaining continuous emission control.

Extreme cold, dusty environments, or frequent stop-and-go conditions can challenge the DPF filter’s ability to regenerate properly. Adapting driving habits or performing maintenance can help mitigate these effects.
