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 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, 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 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 ISX Turbo (OEM 4309079RX) is a vital engine component designed for 2007–2010 Cummins ISX engines. Its primary function is to capture exhaust gas energy and use it to compress incoming air before it enters the engine. This compressed air provides the oxygen needed for efficient combustion, helping the engine operate reliably under demanding heavy-duty conditions. The OEM 4309079RX turbo is designed as a direct-fit replacement for compatible Cummins ISX applications and features a 106 mm compressor housing outlet.
Rather than allowing exhaust gases to exit the engine unused, the turbocharger converts that energy into compressed intake air, making it an essential part of the engine's air management system.
What Does the Cummins ISX Turbo Do?
- Converts exhaust energy into compressed air
- The turbocharger uses exhaust gases to spin a turbine, producing compressed intake air that supports engine operation.
- Supplies oxygen for efficient combustion
- Compressed air provides the oxygen needed for complete and consistent fuel combustion inside the engine.
- Adjusts airflow to match engine demand
- The turbo responds automatically to changes in engine speed and load, delivering the appropriate amount of airflow during varying operating conditions.
- Supports the intake and exhaust systems
- It connects the exhaust and intake sides of the engine, helping maintain balanced airflow throughout the combustion process.
- Works with the engine control system
- The turbo operates alongside the engine control module (ECM) to regulate airflow and support efficient engine operation.
- Promotes dependable engine operation
- A steady supply of compressed air helps maintain smooth combustion and reliable performance for heavy-duty trucking applications.
The Cummins ISX Turbo (OEM 4309079RX) serves as the engine's airflow management system. By converting exhaust energy into compressed intake air, it helps maintain efficient combustion, balanced airflow, and dependable engine operation. Its role is essential in supporting the long-term reliability and efficiency of compatible Cummins ISX engines.
Driving with a failing turbo can lead to several serious issues. A turbo is essential for boosting your engine's power, and when it starts to fail, you may notice a decrease in efficiency and increased risks to other components of your vehicle.
Here are some key risks associated with driving with a failing turbo:
- Engine Damage
- A failing turbo can lead to excessive heat, causing damage to your engine. If left unaddressed, this may result in costly repairs.
- Reduced Fuel Efficiency
- With a malfunctioning turbo, your vehicle will consume more fuel as it struggles to maintain power.
- Increased Emissions
- A failing turbo can cause your engine to produce more harmful emissions, potentially leading to environmental concerns and regulatory issues.
- Loss of Power
- A noticeable drop in power can make it difficult to accelerate or maintain speed, especially on highways or steep inclines.
Ignoring turbo issues can escalate to more severe damage, affecting not just the turbo itself but also the engine and exhaust systems. If you notice signs like unusual noises, excessive smoke, or a loss in power, it's crucial to address the problem promptly. Replacing a failing turbo at the right time can save you from more extensive and costly repairs down the road.
Signs include power loss, excessive smoke, high-pitched whining noises, and increased oil consumption.
Boost leaks, cracked intercooler pipes, or a failing wastegate actuator can lead to a sudden loss of boost.
It optimizes air-fuel mixing, allowing for more complete combustion and reduced fuel consumption.
Regular oil changes, checking for leaks, and inspecting the air intake system prevent premature wear.
