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 ISL SCR Filter (OEM 4330156) operates as a dedicated reaction chamber within the exhaust system, designed to chemically treat harmful gases before they are released. Built for 2014–2020 engines, it plays a precise role in managing emissions through a controlled process.
As exhaust gases exit the engine, they enter the SCR system where Diesel Exhaust Fluid (DEF) is introduced. The SCR filter is where the actual conversion takes place, turning pollutants into safer compounds.
Here’s how it works in a clear sequence:
- Receives exhaust mixed with DEF
- After DEF is injected into the exhaust stream, the mixture flows into the SCR filter.
- Breaks DEF into ammonia
- Heat within the exhaust converts DEF into ammonia, which is the active agent needed for the reaction.
- Triggers a catalytic reaction
- Inside the filter, a catalyst coating enables ammonia to react with nitrogen oxides (NOx).
- Converts harmful gases into safer outputs
- This reaction transforms NOx into nitrogen and water vapor, both of which are far less harmful.
- Allows treated exhaust to pass through
- Once the reaction is complete, the cleaned exhaust continues through the system and exits the tailpipe.
- Operates continuously under the right conditions
- The process depends on proper temperature and DEF dosing, allowing it to work automatically during engine operation.
In essence, the Cummins 4330156 SCR filter works by turning harmful exhaust gases into safer emissions through a chemical reaction, making it a key part of keeping the engine compliant and running within proper environmental standards.
SCR filters don’t come with a fixed replacement interval, so knowing when to replace one comes down to recognizing changes in how the system is functioning. Over time, internal buildup and contamination can reduce its ability to process emissions effectively.
The right time to replace your SCR filter is when it can no longer operate efficiently, even after inspection or cleaning. Waiting too long can lead to further issues within the emissions system.
Here are key signs that indicate replacement may be necessary:
- Ongoing warning lights or fault codes
- If alerts related to the SCR system keep returning, it may signal that the filter is no longer functioning properly.
- Heavy internal deposits
- Excessive buildup from DEF or contaminants can block flow and limit the filter’s effectiveness.
- Reduced system efficiency
- The vehicle may struggle to maintain proper emissions control, especially under normal operating conditions.
- Frequent system interruptions or limited operation modes
- Some vehicles may restrict operation when the SCR system isn’t working as expected.
- Repeated issues despite maintenance efforts
- If cleaning or minor repairs no longer resolve the problem, replacement is typically the next step.
Regular inspections help identify these signs early. Replacing the SCR filter at the right time helps maintain proper system function and prevents more extensive repairs down the line.
It is widely used in commercial trucks, buses, and vocational vehicles operating with Cummins ISL engines in the 2014–2020 range.
Catalyst degradation can reduce emissions conversion efficiency, potentially triggering fault codes and affecting system operation.
Yes, proper function ensures consistent exhaust flow, while restriction or damage can disrupt system balance and trigger alerts.
It features a heavy-duty metal housing and catalyst materials designed to withstand continuous exposure to high heat and exhaust gases.
