    5.0 out of 5 stars Effective tool for testing injectors.
    Reviewed in the United States on April 2, 2025
    Verified Purchase
    This thing works great! I used it to test some old injectors and compare them to the new ones that I'm about to put in the Jeep and I could visibly see the difference in the spray patterns between the old and new injectors. Just a side note, go to any parts store and get a can of brake parts cleaner or carb cleaner and pull the nozzle off. If it has a little white nipple sticking up, you can use it to pressurize the adapter and the injector will spray the cleaner so you can see what it's doing. Just hold the blue adapter in the palm of your hand and use the first two fingers to hold the injector in the adapter because the pressure from the can of cleaner will make the injector fly out. Also, please remember to point the injector in a safe direction and away from your face when you press the button to activate the injector. I found the 1,2 and 5,6 settings to be most effective for basic testing. They will be listed in the instruction manual, but they're basically low and high power single and rapid pulse settings, respectively. Use with caution and I think you'll be very satisfied with it.

    Reviewed in the United States on June 23, 2025

    Why did you pick this product vs others?:
    Saw a review done on it, and the price point was right.
    Ease of installation:
    Very easy and straight forward to use. It gets cumbersome when you try to juggle the solvent cleaner can (carb or brake cleaner) and the device the injector uses to plug into it.

    5.0 out of 5 stars cheap insurance.
    Reviewed in the United States on December 12, 2024

    I was looking to purchase bigger injectors but wanted to take the cheap route- I bought 2 sets of injectors that had less than favorable reviews due to some injectors being DOA- enter this tester to save me the hassle of installing injectors only to learn they need to be swapped. Out of the 8 injectors, this saved me the hassle and found 2 DOA injectors- and all of this cost less than a single injector from the dealer... time and money well spent in my case- and honestly, seems like good practice to test EVERYTHING, regardless of vendor reputation- because duds do happen!
