These Performance Injectors start life as BRAND NEW injectors. They are then precision EDM'd & extrude hone finished according to Engineered Diesel's specifications to flow within +/-1.5% across the set. This creates a much crisper spray pattern resulting in a cleaner burn, which gives YOU more power and efficiency!


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. Good, honest business... 5 Star Review

    Great buying experience, high quality product and extremely resourceful team.

  2. Updated fuel mileage test for 9hour rookie instal 4 Star Review

    Posted by on 22nd Nov 2015

    I would like to add to my original review that after two 34 gallon tank fuel fill ups with the new injectors installed that I actually lost just over 2 miles per gallon however I was sceptical about gaining that much horse power and not losing fuel mileage in the first place.

    Test was ran empty in a 2006 3500 Dodge Ram mega cab dually with 33inch cooper discover maxx mud/snow tires on mostly 4 lane roads nonstop and very few red lights with new royal purple 10w40 oil/filter, new fuel filter and a recently installed Ats exhaust manifold, banks economind six Gun tuner was set on tow haul for the duration of the trip, also there's a banks ram air intake and monster 4 inch exhaust. 213,000+ miles on truck.
    I filled up the 34 gallon tank and also spent extra time and filled the neck of the fuel tank which holds an additional gallon so I could run the test properly. I set my cruise control on 62 mph (1650 rpm) and drove to south Alabama from Atlanta Georgia which I got right at 16.92 mpg and I refilled up and did a return trip with cruise control set at 71 mph (2050 rpm) and got roughly 14.77 mpg. I did drive like a grandpa and did not Gun the throttle any for the test. The massive power increase is still very worth the time and money.

  3. 9 hour rookie easy installation 4 Star Review

    Posted by on 12th Nov 2015

    I've never replaced my stock injectors until I started getting extremely rough idling recently so I replaced tons of sensors and still had the issue. Over 213,000 pulling miles on my 2006 5.9 cummins with $4,500.00 in banks racing/economy upgrades.
    So I removed the beauty cover and tested the valve cover gasket (was good) then disconnected the wiring from the valve cover gasket and tested the injectors themselves using a volt meter, my number 3 injector tested at over 3 Ohms and number 2 injector tested at almost 2 ohms but the rest were good at .08 ohms but I wanted to replace all the injectors at the same time anyways so I purchased the whole kit.

    I'm not a mechanic either so I did the research and found these to be as good as any so I tried them out.
    More HP, slightly more fuel mileage but still testing and it was pretty simple to remove the old injectors and install the new ones with the kit that engineered diesel provided. (Also you will need an inch lbs and a ft lbs torque wrench)

    I received the injectors, new feeder tubes and the tool to remove the old feeders all within 4 days of ordering and used the old packaging to send my old injectors back to engineered diesel to get my core refund which I recieved within 5 business days of them receiving my cores.
    Also I contacted engineered diesel about the ratings etc of these 100HP upgraded injectors and they were always helpful within a day or two. This is one of the answers I got.

    Question: "What CFM are these 100HP injectors?)
    Answer: "The injectors are not measured in cfm. We measure them in MM3 or cubic milliliters. Your injectors flow 160mm3 @ 160 mpa @1700us pulsewidth"

    I did not adjust valve lash, I simply removed the exhaust rocker arms with the middle bolt and replaced them and torqued everything down according to specs.
    They run awesome! Replace them yourself and save the money but don't over torque!!!
