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.

An Air Tube is designed to provide dependable service while carrying air through the engine or emissions system. There is no universal replacement interval because its lifespan depends on the application, operating temperatures, vibration, environmental exposure, and overall maintenance. Routine inspections are the best way to determine when an Air Tube is approaching the end of its service life.
- An Air Tube can often remain in service for several years when operating under normal conditions and properly maintained.
- Constant exposure to high temperatures can weaken the tube material and eventually cause cracks or deterioration.
- Engine vibration may loosen fittings or create stress around mounting and connection points.
- Corrosion, moisture, and road contaminants can shorten the lifespan of metal Air Tubes.
- Physical damage, improper installation, or contact with surrounding components can lead to premature wear.
- Air leaks, cracks, corrosion, or damaged fittings are signs that the tube should be inspected and possibly replaced.
- Regular inspection during routine engine maintenance can help identify developing problems before complete failure occurs.
Rather than replacing an Air Tube at a specific mileage or age, its condition should be evaluated during routine maintenance. Addressing leaks, corrosion, and mounting problems early helps extend service life and maintain reliable airflow throughout the system.
Yes. Excessive vibration can stress the tube, mounting points, clamps, and connections. Worn supports or nearby components should be corrected if they are contributing to repeated damage.
Technicians should check the connecting hoses, clamps, seals, mounting points, and nearby air-handling components. This helps identify other problems that could cause leaks after installation.
Yes. Misalignment, excessive stress, incorrect clamp positioning, or poor sealing can cause premature wear or leakage. The tube should be installed according to the applicable service procedure.
Depending on where the damage is located in the air system, an opening may allow unwanted contaminants or disrupt proper airflow. Any cracked or disconnected air tube should be addressed promptly.
