SHIPPING POLICY

Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. 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 Cummins X15 DOC Filter (OEM 5509707) is a key component in the exhaust aftertreatment system, responsible for initiating the process of cleaning exhaust gases. Designed for 2018–2024 engines, it works by using a catalytic reaction to convert harmful compounds into less harmful substances before they move further downstream.

Unlike filters that physically trap particles, the DOC (Diesel Oxidation Catalyst) focuses on chemical conversion. As exhaust gases pass through the unit, they interact with a catalyst coating—typically made from precious metals—which triggers oxidation reactions.

Here’s how it works step by step:

  • Receives hot exhaust gases from the engine
    • As exhaust exits the engine, it enters the DOC carrying pollutants such as carbon monoxide (CO) and unburned hydrocarbons (HC).
  • Initiates oxidation reactions
    • The catalyst inside the DOC reacts with these gases, converting CO and HC into carbon dioxide (CO₂) and water vapor.
  • Generates heat during the process
    • The oxidation reaction produces heat, which is important for supporting downstream components like the diesel particulate filter (DPF).
  • Passes treated gases further down the system
    • After initial treatment, the exhaust continues to the next stages of the aftertreatment system for additional processing.
  • Operates continuously without additional fluids
    • The DOC does not require Diesel Exhaust Fluid (DEF); it relies solely on exhaust temperature and catalyst activity to function.

In simple terms, the Cummins 5509707 DOC filter acts as the first stage of exhaust treatment, using chemical reactions to reduce harmful gases and prepare the exhaust for further cleaning within the system.

A Diesel Oxidation Catalyst (DOC) filter doesn’t have a fixed replacement interval, so it should be replaced based on its condition rather than mileage alone. Over time, buildup and contamination can reduce its effectiveness, making timely replacement important.

The best time to replace your DOC filter is when it becomes restricted or can no longer properly process exhaust gases. Ignoring early signs can lead to reduced efficiency and added strain on your engine.

Here are common indicators that it may be time for a replacement:

  • Persistent warning lights or fault codes
    • If the system continues to trigger emissions-related alerts, the DOC may no longer be functioning properly.
  • Excessive soot or buildup
    • Visible contamination or internal blockage can restrict exhaust flow and reduce the filter’s effectiveness.
  • Reduced engine responsiveness
    • A clogged DOC can create backpressure, making the engine feel less responsive during acceleration.
  • Increased fuel consumption
    • The engine may use more fuel as it compensates for restricted exhaust flow.
  • Frequent issues with other emissions components
    • Problems with downstream parts like the DPF may indicate the DOC is no longer operating efficiently.

Regular inspections can help catch these issues early. Replacing a worn or restricted DOC filter at the right time helps maintain proper exhaust flow and prevents further system complications.

By oxidizing exhaust gases and increasing temperature, it helps create the proper conditions for DPF regeneration and efficient SCR operation in the system.

A restricted DOC can disrupt exhaust flow, reduce emissions system effectiveness, and trigger fault codes due to improper exhaust gas processing.

This DOC module typically weighs around 29 lbs and is housed in a compact, durable casing designed for integration into heavy-duty exhaust systems.

No, the DOC filter is typically supplied as a catalyst module only, while sensors and wiring are separate parts of the aftertreatment system.
