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.

Diesel engines rely on advanced emissions systems to reduce harmful exhaust pollutants, and the Cummins ISB 6.7L DOC Filter (2018–2022, OEM 5418479) plays a key role in that process. The Diesel Oxidation Catalyst (DOC) filter helps convert carbon monoxide and unburned hydrocarbons into cleaner, less harmful gases before they exit the exhaust system. Using the correct OEM-grade DOC filter ensures your emissions system functions effectively, supporting engine efficiency and compliance with emissions standards.

This DOC filter contributes significantly to exhaust treatment — here’s why it matters:

  • Improves Exhaust Emissions – Helps transform carbon monoxide and hydrocarbons into safer compounds, improving the quality of exhaust output.

  • Supports Downstream Emissions Components – By reducing the pollutant load early in the exhaust stream, the DOC helps downstream systems like SCR and particulate filters work more efficiently.

  • Maintains Emissions Compliance – Installing the correct DOC filter helps ensure your engine continues to meet regulatory emissions standards without triggering warnings or derate conditions.

  • OEM-Grade Fit and Durability – As OEM 5418479, this DOC filter is engineered to match original specifications for size, materials, and performance, providing reliable long-term operation.

  • Prevents Exhaust System Issues – Replacing a worn or clogged DOC filter can help reduce backpressure, improve throttle response, and restore smoother exhaust flow.

A failing or restricted DOC filter can lead to reduced emissions efficiency, increased exhaust temperatures, and potential system warnings. The Cummins ISB 6.7L DOC Filter (OEM 5418479) delivers the OEM-standard quality and emissions support needed to help your engine run cleaner and more efficiently. For engine owners and technicians seeking a dependable replacement, Tamerx offers high-quality parts engineered to support long-lasting emissions performance and overall engine health.

A Diesel Oxidation Catalyst (DOC) filter plays an important role in reducing harmful exhaust emissions in diesel-powered vehicles. While it doesn’t require the same level of attention as some other emissions components, proper oil selection and routine maintenance are still essential to ensure long-term reliability and compliance.

  • No special oil required, but quality matters: DOC filters do not require a unique or dedicated oil type, but using manufacturer-approved, low-ash engine oil helps minimize soot and residue buildup.

  • Routine engine maintenance is key: Regular oil changes, proper fuel system care, and timely engine service reduce contaminants that could affect the DOC filter.

  • Clean fuel supports DOC health: High-quality diesel fuel helps limit excessive hydrocarbons and particulates entering the exhaust system.

  • Monitor exhaust system conditions: Addressing engine issues early, such as incomplete combustion or injector problems, helps prevent unnecessary strain on the DOC filter.

  • No manual cleaning needed: Unlike some emissions components, DOC filters are maintenance-free under normal operating conditions and do not require periodic removal or cleaning.

A DOC filter does not demand special oil or complex upkeep, but it does rely on proper engine care to function effectively. By following recommended oil guidelines and maintaining the engine and fuel system, vehicle owners can support the DOC filter’s role in emissions control and help extend the life of the entire exhaust system.

 

If the DOC filter becomes restricted or fails, the engine’s diagnostic system can trigger warning lights or codes. These alerts help indicate when inspection or service is needed.

The DOC filter is engineered for long service life under normal operating conditions but can vary depending on usage and exhaust conditions. Regular system monitoring helps ensure it performs as expected.

Yes, excessive soot or debris in the exhaust system can cause the DOC filter to clog prematurely. Regular inspection of the aftertreatment system helps prevent excessive buildup.

Installation usually involves aligning the DOC filter within the exhaust system and securing all connections according to factory specifications. Proper sealing and torque help prevent exhaust leaks and ensure performance.
