The Stage 1 injectors are very popular for towing and everyday driving for those looking for a modest power increase coupled with the benefits of converting to a single shot injector. The new single shot design is more efficient and requires a custom tuned chip to achieve the best performance. Power increases are typically between 50-100 horsepower and fuel economy gains are also prevalent due to the more efficient single shot design.
USES FOR STAGE 1:
- Heavy to Light Towing
- Fuel Economy Increase
- Mild Performance Increase
- Stock Turbo
- Stock Transmission
INJECTOR WARRANTY POLICY: The warranty does not cover injectors that fail due to bad fuel or trash in the oil system. This also applies to the replacement of scored plungers and barrel assemblies due to bad fuel or the labor to break injectors down to clean poppet valves from dirty oil.
The buyer is to understand that these are aftermarket, high performance items, and Diesel Power Products is not responsible for any damage caused to the injectors or engine due to high EGTs, overrevving, engine failure or any other abuse or neglect.
If there is an injector problem, the buyer will have to purchase a new injector and send in the faulty injector. The buyer will receive a refund on the new injector after the faulty injector is inspected and determined to be covered by the above warranty.

Does this come with the o rings??
Yes those injectors come ready to install with the orings.
Greetings, I would like to give you a set of Early 99 7.3l injectors as cores and receive back your stage 1 injectors to place in a 2000 7.3l engine in my Excursion. Is this acceptable? The Early 99's are obviously a different type of injector than the 2000 7.3l had. Does this matter given the final application of the injector? Would I lose anything by doing this if you are amenable to doing the work? Thanks, Matt?
If you have an early 1999 7.3, with split-shot AB injectors you will need to replace them with split-shot AB's. If you are going to a Stage 1, which is a single-shot injector you must have custom tuning done, otherwise the it will have issues running. In which case it will not matter what injectors you send in. We charge the core upfront so at the time of purchase you will pay for the injectors AND the core. When the old injectors are received back the core charge will be refunded back on your card.
Is the black plug injector the number 8 injector??
Typically the black plug and AE identifies the Long Lead injector. This injector set will not use a long lead because they are all single shot injectors. The long lead was only used on split shot injectors.
How can I make sure to order the AB type for the early 99 and not the AD version that came on the later 99 to 2003 units??
These are performance single shot injectors that do not use injector codes like you have mentioned.
I'm needing these Injectors for a 94-97 7.3 PS WILL THESE WORK???
No, as the description lists 99-03 model years.

Would I need a chip for these stage 1 injectors for stock 2001 7.3 since there would no longer be a longer number 8 injector??
Yes, you will need to custom tune the truck to run these injectors, as they are a SINGLE SHOT design, and the factory are SPLIT SHOT. -Ben
