THIKPO Fuel Injector Tester Cleaner Tool Kit — Universal 12V EFI/GDI Diagnostic & Cleaning Kit with 8 Adapters

This compact kit combines an adjustable pulse generator, eight cleaning adapters and protective circuits so technicians and DIYers can test injector operation off-engine and deliver cleaning fluid under controlled pulses. It supports most 12V electronic fuel injection (EFI) and gasoline direct injection (GDI) injectors, offers multiple pulse widths and two drive voltages, and includes safety protections for reversed polarity and short circuits.

How does the tester identify injector problems?

The unit mimics ECU output by sending selectable pulse patterns and voltages to an injector so you can observe spray pattern, listen for proper clicking and monitor fuel flow. Running the injector with a pressure gauge or visually inspecting the spray will reveal blockage, leakage, sticking or electrical failure.

• Eight pulse modes (short/medium/long/continuous and high/low voltage) for varied diagnostics
• Two output terminals let you test a single injector or compare two simultaneously
• Built-in LCD shows active mode so you can repeat the same test reliably
• Reverse-polarity and short-circuit protection safeguard the unit and vehicle wiring

What cleaning adapters and fitments are included?

The kit includes eight size adapters that cover a wide range of injector inlet and outlet diameters, plus two specialty fittings tailored for certain European models. Those adapters allow a pressurized cleaning solvent feed to the injector while pulsing it to dislodge deposits and restore spray geometry.

• Eight universal adapters for most 12V EFI and GDI injector shapes
• One VW/Audi-compatible adapter and one BMW N-series threaded adapter
• Adapters work with common cleaning solvents (solvent not included)
• Compatible with external fuel pressure testers for controlled cleaning cycles

How do I power and protect the tester during use?

The tester runs from a 12V vehicle battery or a DC 12V adapter (minimum 1.5A) and features robust, heat-resistant wiring to withstand workshop conditions. Protective circuitry prevents damage from reverse connection or output shorts and alerts you with the power indicator if there’s an issue.

• 40-inch power cord and 20-inch test leads for flexible workshop reach
• Superior silica-gel insulated wires designed for temperature variation
• Indicator light flashes to warn of short circuits or output problems
• Not suitable for diesel mechanical injectors — gasoline systems only

What additional uses and limitations should I know?

The pulse generator can be adapted for testing relays or solenoid valves under professional guidance and pairs well with fuel pressure gauges during off-engine servicing. Remember the kit requires a separate cleaning solvent and a 12V power source; it is intended for petrol injection systems and not for diesel mechanical injectors.

• Can assist with relay/solenoid testing if modified by a knowledgeable technician
• Works in tandem with fuel pressure gauges and pressure testers for off-engine service
• Cleaning solvent and power supply are sold separately — prepare before starting
• Manufacturer provides online technical support and a three-year warranty

Who is this for: the THIKPO kit is designed for automotive technicians, independent mechanics and competent DIYers who service petrol engines and want a versatile handheld tool to diagnose injectors, verify electrical operation and perform pulsed cleaning off the engine. It’s best for garages that require repeatable pulse settings, adapter variety for mixed fleets, and protection features to reduce accidental damage during bench testing.
