EWK Fuel Injection Cleaner Canister Vacuum System Cleaner Intake Valve Pressure Tester

Works as designed. Used it to clean intake systems on all my vehicles. Used SeaFoam cleaner and it works great.

This item worked out for me and my 2008 Infiniti G37s , once the cleaning fluid was filled and the plastic tip was inserted into one of the vacuum lines, the valve on the canister opened with engine running (of course) it looked kinda cool flowing into intake manifold. And It was set it and forget at that point. Once the fluid ran out shut the engine off and let it heat soak for about an hour then with the vacuum hose re installed I drove the car until the smoke cleared and it's been running much better than before. It's a cheap product for it's purpose but I don't do auto repair so it works fine for my level.

Works as intended. A little difficult to adjust the rate at which the cleaner gets sucked in because there is no “window” showing the drops, and it’s of a challenge to determine the rate while the fluid is moving through the tubing

Very good no more to say

Used it . works as described . was easy to use however with no ability to adjust flow rate to much can go in the system resulting in a engine code which i received after the engine shut off. after running engine for a while i erased the engine code and it has not returned of yet . Hopefully it will not return but i would recommend running the engine after it shuts down until all smoke has been removed.
