99-03 Ford 7.3L Powerstroke 175/146 Single-Shot Injectors Tow/Mild Street

99-03 Ford 7.3L Powerstroke 175/146 Single-Shot Injectors Tow/Mild Street



*By checking this box you understand that this is a single shot injector. See Important NOTE below.


Set of 8 injectors. 5 year/200,000 mile warranty!

The 175/146 injectors are a terrific upgrade for those 1999-2003, 7.3L owners looking for efficiency, as well as a modest power increase. The 175 single shot injectors retain the OEM ("146" nozzle), use NO more high-pressure oil than stock AD split shot injectors, yet flow 25+cc's more fuel. "Off the shelf" programmers, and "generic" chips will not work with this style injector, an injection timing and fuel feed rates have to be adjusted to accommodate the single injection event. Reprogramming of TS performance chips, as well as Bullydog chips, are offered at no charge at the time of injector purchase.
The 175/146 single shot injectors have shown to consistently make over 375 rear wheel horsepower, which is a 60hp+ gain, over an already "hot-chipped" Super Duty truck. With our custom tuning, we have been consistently increasing fuel economy 2-3mpg with these injectors!

All Prices Include Brand New Nozzle Assemblies and Internal and External O-rings.

Notes: First 3 digits of the model number are maximum flow rate, second 3 digits are nozzle size. Our "30%" nozzles will flow 30% more fuel than the same injector with a stock "146" nozzle; our "200%" nozzle would flow 200% more fuel in the same amount of time, etc... An "S" before the first 3 numbers indicates a Split-Shot injector. A stock single-shot injector would be 98/146, a stock split-shot S/135/146. Price does not include shipping.

HPOP = High-Pressure Oil Pump, IDM = Injector Driver Module, MM^3 = Cubic millimeters of fuel per injector. Many injector flow benches measure the total fuel volume from 500 or 1000 injector shots. Multiply the MM^3 by 500 or 1000 to convert to CC's flow per 500 or 1000 shots. i.e., 160 MM^3 x 1000 = 160 CC's per 1000 count test, or 80 CC's per 500 count test.

$1,000 Refundable Core Charge Applies. The customer is responsible for core return freight. Please call for core return address before shipping back your core injectors.

Swamp's Motorsports Performance defines CORE INJECTORS as those injectors which were most recently installed into your vehicle's engine. Injectors returned to us, which are out of a salvage yard, injectors which have been burned, or externally damaged, will NOT be suitable as cores. Any injector which has previously been disassembled will NOT be a suitable core injector. If you have any questions these restrictions to your core injectors, please don't hesitate to give us a call.

Please allow 2-3 business days before product ships, please call to check availability if you are in a hurry.
Important NOTE: This is a SINGLE SHOT INJECTOR meaning on 99-03 trucks "Off the shelf" programmers, and "generic" chips will not work with this style injector, as injection timing and fuel feed rates have to be adjusted to accommodate the single injection event.
