    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.

I must also say, WOW. I got this truck 2.5 years ago with 128K miles on it. The power seemed ok and has been slowly getting worst, including the fuel mileage. I used to average 18 to 18.5 MPG on the highway and 16.5 MPG for mixed city/hwy. Recently it dropped to 15.5 on the hwy and averaged 13. With my machine at 185K miles and injectors 1 and 7 starting to fail, it was time to replace. Well, I did the install myself and saved a bunch of money buying from DPP and no labor cost. Relatively easy install. Now, the results. I went to kit the pedal like normal in the parking lot and broke the tires loose. Surprised me a lot. I got on the street and again, WOW. I've never had this much power out of this engine since I've owned it. Took it on the highway, 22.5 MPG @ 70 MPH. WOW again. I haven't towed yet but I'm loving this change so far. I also put the ARP headstuds in while I had the head covers off. No need to stress about the power now. I suggest you get a set of these if you want to let the monster out of the 6.0L. I'm so glad I did.


Those injectors have a 1 year parts warranty on them.


Are these injectors good because I like what I've read about them but don't want to spend all that money and they don't last?

Please contact us and we can talk further about injectors.


will these injectors work with a f250 thst has a sct x4 with custom tunes from gear hesds .do you have to have a custom tune for these specific injectors in order for the truck to idle properly.?

I would recommend getting the tuning changed for the increase in size on the injectors for sure. We would have a couple questions. Shoot us a call on those injectors before you order. -Sands
