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.

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.


Built for 2015–2022 Mitsubishi Fuso 2.2L engines, the Mitsubishi Fuso 2.2 DOC Filter (OEM 31F340-03010) is a key component of the diesel exhaust aftertreatment system. This Diesel Oxidation Catalyst (DOC) filter works to reduce hydrocarbons and carbon monoxide within the exhaust stream before gases exit the vehicle. Manufactured to meet original equipment specifications, it is designed for proper fitment and reliable compatibility with existing emissions components. The durable construction is intended to withstand high temperatures and demanding operating conditions commonly found in diesel applications. Replacing a worn or restricted DOC filter with the OEM 31F340-03010 helps maintain proper exhaust system operation and supports compliance with emissions regulations.

The Mitsubishi Fuso 2.2 DOC Filter (Diesel Oxidation Catalyst), OEM 31F340-03010, is a key part of the exhaust aftertreatment system used in Mitsubishi Fuso 2.2L engines from 2015 to 2022. Its job is to begin the process of treating exhaust gases by converting harmful compounds into less harmful ones before they move through the rest of the system.

Inside the DOC filter is a honeycomb structure coated with catalytic materials. As hot exhaust gases pass through this structure, chemical reactions take place that change the composition of certain pollutants.

How the Mitsubishi Fuso DOC Filter Works

  • Exhaust gases enter the DOC unit
    • Exhaust from the engine flows into the DOC as the first stage of the aftertreatment system.
  • Catalytic reactions occur inside the filter
    • The catalyst coating reacts with hydrocarbons (HC) and carbon monoxide (CO) in the exhaust stream.
  • Pollutants are converted
    • These reactions transform harmful gases into carbon dioxide and water vapor.
  • Heat is generated during the process
    • The oxidation reaction increases exhaust temperature, which helps prepare gases for downstream components.
  • Exhaust moves to the next stage
    • After passing through the DOC, the treated exhaust continues to the Diesel Particulate Filter (DPF) and other emissions components.

Why This Process Is Important

By starting the emissions treatment process, the Mitsubishi Fuso DOC Filter OEM 31F340-03010 helps ensure that the rest of the aftertreatment system receives properly conditioned exhaust gases. This allows the system to function effectively and maintain emissions compliance.

A Diesel Oxidation Catalyst (DOC) filter is a key component in a diesel vehicle’s emissions system. It helps convert harmful exhaust gases into less harmful compounds before they exit the vehicle. When the DOC filter fails, it can lead to warning lights, emissions issues, and restricted exhaust flow.

The most common cause of DOC filter failure is contamination of the catalyst surface. When foreign substances enter the exhaust stream, they can coat the catalyst and prevent it from properly treating exhaust gases.

Several factors can lead to this type of contamination, including:

  • Excessive soot buildup
    • from incomplete combustion
  • Oil entering the exhaust system
    • due to engine wear or leaks
  • Coolant leaks
    • introducing harmful deposits into the catalyst
  • Poor fuel quality
    • that leaves residue behind
  • Unburned fuel
    • reaching the exhaust from engine issues

Driving habits can also contribute to DOC filter problems. Vehicles that frequently make short trips may not reach the temperatures needed to burn off soot, allowing buildup to accumulate over time.

Routine maintenance and addressing engine issues early can help prevent contamination and extend the life of the DOC filter.

An issue with the DOC filter may lead to abnormal exhaust system readings or warning indicators.

The gases undergo catalytic reactions that convert certain compounds into less harmful substances.

Technicians verify compatibility by matching OEM number 31F340-03010 with the engine and model year.

It is designed to function under high exhaust temperatures and continuous operation typical of diesel engines.
