Great Upgrade for Stock Trucks! (and relatively stock trucks) 


*Replaces your STOCK injectors with NO additional modifications required to run! This means YOU get more power at STOCK prices! Just bolt-on and go!*



OEM FEED TUBES - It is highly recommended to replace the connector tube at the time of injector replacement. If an old connector tube is re-used, it can introduce debris into the system or a repeat leakage failure can occur, damaging the body of the new injector (which is not a warrantable failure). 


**WARRANTY: 1yr/unlimited mileage warranty, unless otherwise specified. Covers manufacturer defects and faulty workmanship. DOES NOT COVER FAILURE DUE TO DEBRIS IN THE INJECTOR, BAD FUEL, DIRTY INSTALL, FAILED FEED TUBES, ETC.  ALSO NOT COVERED: damage due to water, gasoline, or other contaminants in the fuel. Operating any injector on any fuel other than commercially available petroleum diesel including biodiesel and any homemade blends may result in jeopardizing the warranty. If the injectors are being replaced due to contaminated fuel, the feed tubes must be replaced. All customers are highly advised to use Stanadyne performance formula diesel fuel additive!**

  1. 200,000 mile truck better than new 5 Star Review

    Posted by on 26th May 2015

    Engineered diesel really has a great product with these injectors. I bought the feed tubes and tube tool, which was great. I'd do this again in a heartbeat. Very quick delivery and good customer service made this as painless as spending a butt-load of money can be.

  2. 50 hp injectors 5 Star Review

    Posted by on 1st Oct 2014

    I had a seamless transaction. I installed the new injectors and feed tubes with no problems. During the test drive I could feel the improved throttle response. I can't wait to check the mileage.

  3. Great product and great Service. 5 Star Review

    Posted by on 14th Sep 2014

    Best price you can find for a quality injector. I received my injectors the next day after ordering them. Engineered Diesel has great customer service. All my questions were answered over the phone and I was even called back with the tracking information shortly after my order was placed. I would highly recommend Engineered Diesel for any parts; especially If you need a new set of injectors!
