Trucks built before 12/7/98 are early 99 and use "AB" split shot injectors.
Trucks built after 12/7/98 are late 99 and use "AD" split shot injectors.

Any vehicle with split shot injectors can be modified to run with the more efficient fueling of single shot injectors. However, special Swamps programming is required to modify ECM fueling tables which allow the single shot injectors to function properly in a system tuned to fuel a split shot system.

The First 3 digits of model number is maximum flow rate, second 3 digits are nozzle size, An " S" before the first 3 numbers indicates a Split-Shot injector. A Single-Shot injector will not have the S prefix

There will be a Core Charge of $1000 if your working Injectors are not returned to SWAMPS DIESEL PERFORMANCE within 21 days of receipt of the product.
This will be charged in $50 dollar increments for up to 20 days, so if you return your injectors after 31 days you will be charged $500 in late fees.
Please note that these prices are based on you returning
a set of injectors in good working order.
If the Plunger and Barrel assembly is scored or damaged,
you will be charged $60 for each one.
Nozzle condition is not important, because we install Brand New Nozzles
in all our injectors except for the 150/146.
All prices include Internal and External O-rings.

Injectors are shipped without oil deflector spouts -
you will need to install the ones from your injectors
onto the new injectors.

Stage 1- S/175/146 Split Shot Injectors -up to 30 H/P over Stock -This is the mildest injector for the 1999-2003 7.3L Powerstroke. By retaining the stock nozzle size, low end overfueling is all but eliminated. Perfect for towing heavy loads, without the worry of excessive exhaust gas temperatures, loss of mileage, and excessive smoke. This is a very mild injector and will work with normally programmed chips. To get the maximum performance out of this injector we recommend the Swamps Hot programs.

The 175/146 injector might be considered a "Stage 1.5" single shot injector... It has the ability to flow more fuel than any other companies "Stage 2" injector, but due to the efficiency of the single shot event combined with a very small nozzle, more power  and more economy can be had similutaneously. Gains of 30 to 40 HP are normal with this injector. We recommend this style injector for the 99-03 Powerstroke owner who 'works' his truck, wants a mild performance increase, but will not be entering competitive events with an intent on winning. This injector and our custom tuning has increased the mpg on over a dozen Super Duty's from 12-14 mpg to 16-18 mpg consistently. We actually have customers obtaining an "honest" 20mpg with crew cab 4x4 trucks.

This injector will fuel more heavily than the 175/146, making it a good choice for the owner who (has, or) will install a larger than stock turbocharger. A stock turbo will fail over time with the added fuel flow demand. Towing heavy loads is not recommended without an upgraded intercooler & turbo.

Stage 2.5 - S/175/173 Split Shot Injectors - 60-70 H/P over Stock- The larger nozzle on this stage II will dramatically increase the bottom end power, without starving for fuel on the top end. This injector will fuel more heavily than the S/175/146, making it a good choice for the owner who (has, or) will install a larger than stock turbocharger. A stock turbo will fail over time with the added fuel flow demand. Towing heavy loads is not recommended without an upgraded intercooler & turbo. Swamp's chip programming is highly recommended to take full advantage of the injectors performance potential. "Off the shelf" chip/programmers will work fine with this injector but will produce less fuel efficiency and more black smoke

Wild ! Stage 3 - Race 250/173 Single Shot Hybrid Injectors- 150 - 250 HP over Stock -This injector is much like a sleeping dragon. With mild Swamp's programming on your chip, this injector can be 'tuned down' to a HP level that is not only streetable, but downright enjoyable. Conversely, this same injector can be tuned up (via Swamp's programming) to a level that obliterates rear tires, and much of the competition...and anywhere in between. True Yin-Yang Performance. Full performance from this injector will only be realized with the addition of a high volume fuel system, and a high pressure oil pump that can maintain the pressure desired by the engine computer (or chip). A Turbo upgrade is a must if you are considering these larger nozzle injectors. A stock turbo will fail over time with the added fuel flow demand. This hybrid injector is unique, in that while delivering more than 250% more fuel (than a stock 'AA code' injector at maximum flow), it uses no more high pressure oil than a stock 'AD code' injector.

Warranty
We make no guarantee as to these injectors' fitness or suitability for any intended purpose. Our only claim is that they will flow the amount of fuel listed for their particular specifications.
If problems in the nozzle assembly, poppet valve, amplifier piston or plunger spring occur within the first year, we will repair it at no charge to you.
You pay shipping to return it to us, and we pay ground shipping to return it to you. We are not responsible for the associated costs to remove or reinstall the injector in the engine, nor for towing costs, rental vehicles or any other cost directly or indirectly related to the injectors. We only cover problems related directly to our modifications. i.e., if you return a malfunctioning injector, and it is found to be caused by fuel contamination, as evidenced by a scored plunger or barrel, that is not warrantied. Individual malfunctioning injectors may be returned for repair or replacement, but we do not accept returns of sets that have been installed in an engine. We are not responsible for engine damage related to or caused by over-fueling, excessive exhaust gas temperatures, turbocharger over-speeding or over-boosting, oil dilution from fuel, or any other factor that may or may not be related to these injectors, nor for problems directly or indirectly caused by malfunctioning injectors. Assume that the Ford factory warranty on your engine is voided the moment you install any of these injectors.
Return Shipping
Injectors are heavy and have sharp points/corners that can cut through packaging. We recommend first wrapping each one in 2-3 shop towels for padding and to absorb the oil in them, then enclosing them in a Zip-Loc bag or several layers of plastic wrap. Next wrap them in newspaper and pack them tightly in the box. A set of injectors weighs about 25 pounds, so be sure to use a strong box in good condition. Proper packing means that the container can be dropped from a height of 18" 6-8 times on its corners, edges and sides with out damage to the contents, and the container remains intact. We do NOT file insurance claims on damaged injectors if they are not properly packed.
Please put your name, address and phone and order number inside the box with the injectors!
