    This injector upgrade is perfect to improve mpg, works great with a stock turbo, and it's the best single shot injector to replace the stock OEM injectors to retain similar driving characteristics. The power made is very noticeable in all driving conditions from off idle to full throttle. This injector set features internal modifications for extra fuel and converted from split shot to the single shot. With modifications to the internals the injectors can flow 180cc of fuel which creates more power. These FFD Reman injectors have low smoke and single shot efficiency which is the best injector for a mild power increase with emphasis on towing and economy. New nozzles, new plunger and barrels, new internal seals and injection springs. Flow tested and match sets of 8 ready to install.

    Choose these injectors for:
    • Great for towing
    • Great fuel economy
    • Low smoke
    • Lower EGT's
    • Works well with stock transmissions, turbos, and fuel system
    • Chip with Single Shot tuning is required
    Stage 1 Injectors are the best selling fuel economy and towing injector we offer. It's the most simple injector. Internal modifications produce a modest increase in fuel production while keeping the stock size nozzle. Improved performance when you don't want to upgrade other parts of your truck.

    Warranty: Full Force Diesel Injectors include a 18 Month Unlimited Mileage Warranty!

    Tuning Information
    New Gearhead Low Smoke Tuning. We now offer low smoke *Clean tuning. In a time when clean tuning is more desired we've step up to the plate. The days of "Clouds of Black Smoke" are behind us. We have partnered with a very reputable tuning company for the lowest/minimal smoke with modified injectors while maintaining optimal power output. Normal driving will yield very low smoke levels and very good power. Foot to the floor will make moderate smoke on the highest setting. Results of this custom tuning typically results in very good smoke control but smoke may vary. Tunes included are hi-idle, heavy tow, tow, street, hot street, and extreme. During the order process please indicate any further tune request you may need. HPOP, Transmission, etc. They will be custom written for each truck.

    Frequently Asked Questions:

    If you currently do not have a Hydra or TS Chip, select a Hydra or TS Chip option. This is required to convert the computer to a single shot fuel injector program. All tunes will add the appropriate power. Tunes included (*for most trucks) Heavy Tow, Hi idle, Light tow, Daily, Race and Extreme tunes.

    Reburn my chip for free: If you have a Hydra or TS Chip we'll put our tunes for the injectors onto your chip. Select "free reflash" meaning you send us your chip (Hydra or TS) and we will reprogram and send it back to you. Hydra emailed tunes ($60) is just that we encrypt the tunes and email them to you for self install. Our Standard tunes typically work great on most trucks. In some cases, our Standard tuning may not work exactly the way you would like. Example: Shifting to hard, to soft, to soon, to late, etc.. At this point your truck would require custom tuning so that you can get tune revisions within 30 days of purchase from the custom tuning company. We cannot revise nor make any changes to our Standard tuning. 

    Core charge: Every injector set requires a core charge. Please select add core to send your injectors now and refund the money later. Best way to not have down time with your truck. Or sending in first for us to wait and sent your order when we get yours to avoid paying the charge.

    Ordered stage 1 injectors and ts chip. Contents were well packaged. Injectors really brought this thing to life. It would be cool to know how much a stock injector after 22year and 300,000 miles is flowing. from the difference I can feel, not very much. Any I've bough from these guys in the past and experience has been great. Keep up the good work

    Made a huge difference between my chipped 7.3 to now. Seems like the power is endless! Idles great and got me 2+ miles to the gallon with my foot in it over my old injectors. Only pulled my trailer (10k toy hauler) around the block but seems like I’ll have zero issues. Thanks again Rob at FFD for helping me with all the parts!
