    Terms & Conditions

    We at Diesel Power Products offer a deferred core program in which we allow you to defer the typical upfront core charge when purchasing via credit card payment. All cores, whether the core charge was deferred or not, must be returned within 21 days from delivery date of product requiring core charge. Failure to do so can result in forfeiture of the entire core charge return. In the event you originally deferred the core charge, you authorize Diesel Power Products to charge you for the core charge.

    All cores must be returned to the original warehouse that original shipment was sent from. If a return label is provided in the original shipment, use this tag. If one is not included, contact us immediately, and we can provide you with the correct address of where the core(s) must be returned to, as well as an RMA (Return Merchandise Authorization) number. DO NOT rely on the return address on the original label as a source for where to ship to.

    If cores are shipped to the incorrect warehouse, your core money will be returned less the shipping cost for us to send the core(s) to the correct warehouse, or if you deferred the core you may be charged for the shipping amount.

    Cores that have been disassembled and/or have missing and/or damaged major components will not receive full core credit. Returned cores must be on a "like-for-like" basis, meaning that the returned core has the exact same fitment as the remanufactured component that was purchased. In the event that the core is not "like-for-like," your core may not be eligible for return / credit.

    Diesel Power Products has the right to alter this policy (i.e. extend the terms) for any reason. If you have an outstanding circumstance, contact us.

    What is a "Core Charge"?

    In order to understand what a core charge is, you must first understand what a core is. In the automotive industry, most products are manufactured from brand new materials. However, numerous products are also remanufactured, meaning that the manufacturer of the product takes a used product, typically removed from a vehicle, disassembles, and replaces all worn components of the master product. A great example of this is in regards to automatic transmissions in which the manufacturer takes an existing transmission, replaces all of the inner working components, such as the torque converter, valve body, etc. and merely reuses the case.

    Because aftermarket manufacturers require a steady stream of incoming cores to build, they charge a deposit on the core, known as a core charge, that is refunded upon receipt. In some cases, the core is not reusable, such as in the event of a cracked case, at which point the core deposit would not be credited as the core component is not reusable.

    If you plan on returning your core you have two options.

    OPTION 1:
    You can accept it, which means you will be charged for the part AND the core at time of purchase. You still have the option to send it back, and if you do, the core will be refunded back on the card used, presuming the core meets core criteria and the core is returned within 21 business days from originally receiving your order. If you have outstanding circumstances that would not allow the return to occur within 21 days, please contact us.

    OPTION 2 You can defer the core charge. If you defer it, you will not be charged a core at time of purchase. You will have 21 business days from the day you receive it to send it back. As long as the core is received within the 21 business days, you will not be charged. If 21 business days goes by and you do not send it back, the card on file will be charged the core amount. You still may send it back, and once received, we will issue the core amount as in store credit, pending any limitations as set forth by the manufacturer.Core deferral is limited to payment by credit card only.

If you're looking for a set of performance injectors for your Cummins, keep reading. Dodge has notoriously had injector failure issues on the Common Rail Dodge trucks. The problem persisted so much that Bosch redesigned the injectors to a new stainless steel body in Fall of 2009. So here's the problem, when you buy aftermarket performance injectors, they are typically going to be remanufactured injectors from somewhere else than Bosch, which many times means you're getting the older style Bosch injectors, which are prone to failure. At the very least, you're getting used, locally remanufactured injectors.

The absolute BEST performance injector will start out as a Genuine OE Remanufactured injector, and then be flowed and matched as a set, not hundreds of injectors at a time that "should" match. That's where we come in. We offer custom honed injectors that we get directly from the manufacturer that are flowed one set at a time upon each individual order. We have the capability to take a stock injectors that will flow an average of 23 lpm (liters per minute) and run a media through it which will hone the nozzle to either 27 lpm or 29 lpm, depending on what we want the outcome to be. An injector flowed at 27 lpm will typically net an average of 50 horsepower over stock, and 29 lpm will produce about 90 horsepower over stock.

For those looking to gain some fuel economy and power, but not wanting to produce tons of power or have to upgrade the CP3 injection pump, then the 50 horsepower would be best suited. For those looking to gain appreciable power and are not opposed to upgrading the CP3 or at least install a Industrial Injection Bag-of-Parts CP3 Upgrade kit, then the 90 horsepower hone would be best.

If you already have known good injectors and want a little (or a lot) increase, we can also take your existing injectors and hone and balance them. If you are unsure of the integrity of your injectors, you can always send them in, because we will test them prior to honing to make sure they are not too badly worn.

Advantage: The advantage to being rebuilt by the original manufacturer is they have the ability to completely "gut" these injectors from input to output to ensure they are as close to new as possible. The only "Remanufactured" part of these injectors is the housing. All internals are brand new and put together the right way. There's no reason to pay enormous costs at the dealer. True Brand New Injectors are not available except for directly on a new truck. If you can get a Brand New Injector, the cost is usually about $800-900 per injector.

  • These are a custom product that is produced as ordered, and will typically take several days for the modification process. Please contact us for lead times as these can vary.
