FOXWELL JT410 Fuel Injector Tester & Cleaner Machine, 4-Cylinder Ultrasonic Injector Cleaner with Heating, Featuring Visual Spray Pattern & Flow Rate, Resistance & Leak Test for 12V Injectors

About this item

• [Ultrasonic Cleaning - Restore Injector Performance] This 4-cylinder fuel injector tester & cleaner machine adopts 38kHz ultrasonic technology with 45°C/113°F heating - the optimal temperature where cavitation effect reaches peak intensity. At 45°C/113°F, it is hot enough to dissolve stubborn carbon, varnish, and sticky residue on fuel injectors, yet safe enough to protect internal seals and components. The powerful cavitation delivers deep internal and external cleaning, restoring injector performance for smoother idle, better fuel economy, and stronger acceleration.
• [Flow & Spray Test - Fast Fault Detection] Four transparent graduated cylinders (140mL each) allow side-by-side comparison of spray patterns and flow rates across multiple fuel injectors simultaneously, with each cylinder clearly marked so you can easily measure the volume of test liquid delivered by each injector per pulse cycle. Watch the spray pattern in real time - no guesswork, instantly identify which injector is clogged, leaking, or operating unevenly.
• [Multi-Mode Digital Control - Simulate Any Driving Condition] Equipped with an intelligent digital display, this fuel injector tester lets you precisely adjust pressure, pulse width, pulse count, and cycle time to simulate a full range of engine operating conditions - from smooth idle to high-speed running at 100-9900 r/min. Complete multiple test modes including idle speed testing, mid/high-speed testing, leak testing, cumulative testing, and auto testing. No need to install injectors back into the engine - you can identify performance issues on the workbench before they cause problems on the road. Professional-level diagnostics made simple.
• [Leak Test - Save Fuel, Drive Smooth] With adjustable pressure up to 8 bar, you can perform a precise leak test on fuel injectors by increasing pressure to instantly detect whether any injector is leaking. A leaking injector drips fuel when it shouldn't - this not only causes rough idle, hard starting, and poor acceleration, but also wastes significant fuel over time. By detecting leaks on the workbench before reinstalling, you can avoid costly fuel loss and ensure every drop of fuel is burned efficiently.
• [Resistance Test - Save Time & Cost] Quickly perform a resistance test to check injector consistency across all 4 cylinders. If one unit reads significantly higher or lower, you’ve found the culprit before wasting time or cleaning fluid. Then run a standard fuel injector tester procedure to pinpoint issues. Only clean injectors in good working order, then retest to confirm perfect function. It’s a cost-effective, no-waste workflow that saves hours of trial and error.
• [Leak-Free Design - Clean & Hassle-Free Operation] Say goodbye to leaking seals and messy spills. Featuring rugged aluminum alloy construction and a precision sealing system, this automotive fuel injector tester & cleaner machine effectively prevents leaking. It supports one-click automatic liquid return to transfer fluid from cylinder units back to the tank, and the built-in drain valve enables convenient reuse of test fluid.
• [Wide Compatibility - Fit Most 12V Injectors] Comes with assorted injector connectors and adapters to fit most 12V fuel injectors for cars and motorcycles. This fuel injector cleaner kit is not compatible with diesel and GDI systems. To ensure optimal performance and extend service life, please use dedicated test liquid and cleaning liquid separately, and do not mix the two.
