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.
Designed for use with Cummins B6.7 and L9 engines, the DPF is an essential component of the diesel exhaust aftertreatment system. This diesel particulate filter is engineered to match the specific exhaust configurations and emissions sensor locations of the B6.7 and L9 platforms, ensuring proper compatibility with factory exhaust assemblies. Its primary role is to capture soot from exhaust gases, helping reduce particulate emissions and support compliance with applicable emissions requirements. Consistent DPF operation helps maintain stable exhaust flow and can help reduce the likelihood of warning lights, fault codes, or derate conditions tied to emissions system issues. This page provides clear application details to assist with identifying the correct Cummins B6.7 and L9 DPF for service and replacement needs.

You can prolong the lifespan of a DPF (Diesel Particulate Filter) by managing soot buildup, allowing proper regeneration, and keeping the engine and emissions system in good condition. The DPF is designed to trap particulate matter, but it depends heavily on operating conditions to clear itself.
One of the most important factors is allowing complete regeneration cycles. Regeneration requires sustained exhaust temperatures, which are typically reached during longer, steady driving. Vehicles that are driven mostly on short trips are far more likely to experience premature DPF problems.
Effective ways to extend DPF lifespan include:
- Allow full regeneration cycles
- Drive at consistent speeds long enough for exhaust temperatures to rise and burn off accumulated soot completely.
- Limit excessive idling
- Idling creates soot without producing the heat needed for regeneration, accelerating filter loading.
- Use the correct low-ash engine oil
- Proper oil reduces ash buildup, which cannot be burned off and permanently reduces DPF capacity.
- Address injector and sensor issues promptly
- Faulty injectors, EGR problems, or failed sensors increase soot production or prevent regeneration from occurring.
- Respond early to warning lights and fault codes
- Addressing DPF alerts early helps prevent minor soot loading from becoming severe restriction.
- Maintain proper fuel quality
- Poor fuel quality increases particulate output and places additional strain on the filter.
In summary, a DPF lasts longest when regeneration is allowed to complete, contamination is minimized, and issues are corrected early through proper driving habits and consistent maintenance.
The diesel particulate filter captures soot particles from exhaust gases before they exit the exhaust system.
The DPF is positioned downstream of the diesel oxidation catalyst.
Yes, it operates as part of the SCR-era exhaust aftertreatment configuration.
It collects soot generated during normal diesel combustion.
