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.

Modern heavy-duty diesel engines rely on advanced exhaust aftertreatment systems to meet strict emission regulations. The Cummins X15 SCR 2018–2024: OEM 5418105 is a Selective Catalytic Reduction (SCR) component designed to reduce nitrogen oxide (NOx) emissions produced during combustion. This SCR unit works within the exhaust system to help convert harmful gases into safer compounds before they exit the vehicle.

  • Designed for Cummins X15 engines from 2018 to 2024, the OEM 5418105 SCR fits directly into the engine’s aftertreatment system for proper installation and compatibility.

  • SCR technology works by injecting diesel exhaust fluid (DEF) into the exhaust stream where it reacts with nitrogen oxides and converts them into nitrogen and water vapor.

  • This process helps significantly reduce NOx emissions, which are among the most regulated pollutants produced by diesel engines.

  • A properly functioning OEM 5418105 SCR unit helps maintain stable exhaust chemistry and supports the overall efficiency of the emission system.

  • Correct SCR operation supports precise DEF dosing, which is necessary for consistent emission reduction and proper exhaust flow.

  • Installing the correct OEM SCR component helps minimize the risk of emission warnings, diagnostic trouble codes, and system faults.

  • The SCR catalyst structure is engineered to withstand high exhaust temperatures and the demanding conditions typical of heavy-duty truck operation.

  • Replacing a worn or restricted SCR assembly helps restore proper aftertreatment function and maintain compliance with modern emission standards.

Choosing the Cummins X15 SCR 2018–2024: OEM 5418105 from Tamerx Diesel Parts ensures your emission aftertreatment system is equipped with a component designed for your engine’s specifications. With the correct SCR unit installed, your truck can maintain cleaner exhaust output and dependable emission control for daily operation.

 

The Selective Catalytic Reduction (SCR) system is a critical part of a modern diesel engine’s emissions setup. It works by injecting Diesel Exhaust Fluid (DEF) into the exhaust stream to reduce nitrogen oxide (NOx) emissions. Because the SCR system is electronically monitored, even a small issue can trigger a warning. If something goes wrong, it can absolutely cause the check engine light to turn on.

  • The engine control module constantly monitors SCR components such as NOx sensors, DEF injectors, temperature sensors, and DEF levels. If any of these parts send irregular readings, the system may activate the check engine light.

  • Low, contaminated, or incorrect DEF fluid can disrupt proper dosing. When the SCR system cannot operate as intended, fault codes are stored and the warning light may appear.

  • A clogged DEF injector or restricted SCR catalyst can prevent proper exhaust treatment. This imbalance is quickly detected by onboard diagnostics.

  • Wiring issues or failed sensors within the SCR system can also trigger emissions-related trouble codes, leading to an illuminated check engine light.

  • In some cases, if the problem is not corrected, the vehicle may enter a reduced power or derate mode to maintain emissions compliance.

If your check engine light comes on and the cause is linked to the SCR system, prompt diagnosis is important. Addressing SCR-related issues early can help prevent further emissions problems, avoid reduced engine power, and keep your diesel vehicle operating as intended.

Warning lights on the dashboard, engine derate conditions, or recurring emissions codes can indicate a problem. These alerts often occur when the SCR system cannot properly convert exhaust gases.

Diesel exhaust fluid is injected into the exhaust stream before the gases reach the Cummins X15 SCR 2018-2024: OEM 5418105. The fluid reacts with exhaust gases inside the catalyst to reduce nitrogen oxide emissions.

Contaminated DEF, faulty sensors, or catalyst wear can decrease SCR efficiency. These issues can prevent the system from converting NOx effectively.

If the SCR system detects emission faults, the engine control module may limit engine power. This protective measure helps ensure emissions compliance and prevent system damage.
