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.

Clogged or degraded Diesel Particulate Filters (DPFs) can increase backpressure, reduce fuel efficiency, and even trigger forced regenerations—making the OEM 20R8020 filter a critical solution. Precisely engineered to meet Caterpillar’s original specifications, this genuine replacement ensures optimal filtration of soot and particulates, safeguarding your aftertreatment system’s integrity.

  • Reliable Soot Capture
    The OEM 20R8020 DPF traps particulate matter efficiently, helping to prevent contamination further downstream in your aftertreatment system. A clean filter supports smoother combustion and protects downstream components from excess soot exposure.

  • Supports Optimal Regeneration
    Proper regeneration requires the right exhaust temperature and flow. A new OEM filter promotes consistent gas flow and helps maintain required thermal profiles, reducing instances of incomplete or uncontrolled regen cycles.

  • Reduces Backpressure and Improves Fuel Efficiency
    Over time, clogged DPFs increase exhaust backpressure—forcing the engine to work harder. Swapping in a new OEM filter with clean flow characteristics helps reduce drag, potentially improving fuel economy and engine responsiveness.

  • One-Year / One-Million-Mile Warranty and Straightforward Replacement
    Backed by a robust warranty, the OEM 20R8020 offers both long-term reliability and peace of mind. Its direct-fit design ensures hassle-free replacement with minimal downtime.

  • Streamlined Core Return for Ease and Savings
    The core charge system is designed to be simple—return the old DPF within the allotted time frame, and your deposit is refunded promptly, keeping servicing efficient and cost-effective.

Maintaining clean exhaust flow is essential not just for emissions compliance, but for the health of the entire aftertreatment system. When your DPF is due for replacement, the OEM 20R8020 offers an exact-fit, durable solution engineered to uphold performance—mile after mile.

A Diesel Particulate Filter (DPF) plays a critical role in reducing soot and emissions from diesel engines. Over time, soot accumulates in the filter and can hinder engine efficiency if not properly cleaned or serviced. To keep your diesel vehicle running smoothly, knowing the right DPF maintenance schedule is essential.

Recommended DPF Service Intervals

  • Passive Regeneration (Frequent Highway Driving):
    If your vehicle regularly drives at highway speeds, passive regeneration may burn off soot naturally, reducing the need for manual servicing. However, even in these conditions, a professional inspection is recommended every 100,000–120,000 miles.

  • Active Regeneration (City or Short Trips):
    In stop-and-go or short-distance driving, soot builds up faster. If active regeneration cycles are frequent or incomplete, it’s wise to have the DPF professionally cleaned around 80,000–100,000 miles or sooner if symptoms appear.

  • Ash Accumulation:
    Unlike soot, ash from engine oil doesn’t burn off during regeneration and requires physical removal. Ash buildup typically necessitates DPF cleaning or replacement between 120,000–150,000 miles.

  • Warning Signs That Require Immediate Service:

    • Reduced engine power

    • Frequent regeneration cycles

    • High fuel consumption

    • DPF or check engine light illuminated

  • Severe Duty Applications (Towing, Heavy Loads, Idling):
    Vehicles used in severe-duty cycles may require DPF cleaning as frequently as every 50,000–75,000 miles due to higher soot production.

While driving habits and engine conditions influence service intervals, most diesel engines benefit from DPF cleaning between 80,000 and 120,000 miles. For best results, consult your engine manufacturer’s guidelines and respond quickly to warning signs. Staying proactive with DPF maintenance helps improve fuel efficiency, prevent costly repairs, and keep emissions in check.

It can lead to restricted exhaust flow, increased regenerator activity, elevated backpressure, and engine damage.

Frequent stop-and-go cycles, insufficient high-temperature drive patterns, or contamination from unburned oil or coolant can degrade the filter.

Soot streaking around the filter housing or clogged perforations at the exit side suggest excessive accumulation.

Confirm the filter is cool and depressurized to prevent accidental burns or damage during handling.
