THIKPO Fuel Injector Tester and Cleaner Kit — 12V EFI/GDI, 8 Adapters & Adjustable Pulse

The THIKPO Fuel Injector Tester and Cleaner Tool Kit is a portable diagnostic and cleaning system that simulates engine pulse signals to test and clean petrol electronic fuel injectors quickly and accurately.

This compact kit combines an adjustable pulse generator, universal cleaning adapters, and high-temperature wiring so you can diagnose spray patterns, detect leaks or blockages, and apply a pressurized cleaning solvent off-engine or in-line. It’s designed for 12V gasoline vehicles with EFI and GDI injectors and includes specialized adapters for some BMW and Audi applications.

How does the pulse generator improve injector diagnosis?

The built-in pulse controller offers eight test modes (four pulse lengths with two drive voltages) so you can reproduce a variety of injector operating conditions. That flexibility helps reveal problems that only show under certain duty cycles or voltages, such as intermittent spray faults or weak opening.

• Four pulse lengths: short, medium, long, continuous.
• Two drive voltages: high (12V) and low (5V).
• Reset switch for quick mode changes during testing.
• Indicator lights signal output and fault conditions.

Can this kit clean different injector types and sizes?

The kit ships with eight different cleaning adapters to fit most 12V EFI and GDI injectors, plus two specialty fittings for Volkswagen/Audi and threaded BMW N-series injectors. Using the correct adapter creates a sealed connection so pressurized cleaning solvent and pulse cycling effectively remove deposits without damaging the injector tip.

• Eight universal-size adapters for broad compatibility.
• One adapter optimized for VW/Audi style injectors.
• Threaded adapter for BMW N-series injectors (N14/N18/N20/N26/N53/N54/N55/N63/S63).
• Works with external fuel pressure testers for off-engine cleaning.

What safety and protection features does the tool offer?

THIKPO designed the unit with multiple safeguards to protect both the tool and the vehicle’s electronics. Reverse polarity protection prevents damage from incorrect battery connections, and short-circuit protection alerts you via flashing LEDs if an output fault occurs.

• Power input reverse connection protection.
• Output short-circuit protection with visual indicator.
• Silica-gel insulated wires rated for varied temperatures.
• Recommended operation at normal ambient temperatures for best performance.

How is the kit powered and what additional items are required?

The tester runs from a 12V battery or an external 12V DC adapter (minimum 1.5A). Cleaning requires a separate injector solvent or cleaner and a compatible fuel pressure tester if you plan to work off-engine; these consumables and power sources are not included.

• Compatible with 12V vehicle battery or 12V DC adapter (≥1.5A).
• Not suitable for diesel mechanical injectors—gasoline engines only.
• Cleaner solvent and power source must be provided separately.
• Can be adapted for relay or solenoid testing with professional guidance.

Who this is for: The THIKPO Fuel Injector Tester and Cleaner Tool Kit suits DIY mechanics, independent shops, and fleet technicians who service petrol EFI/GDI vehicles and need a versatile off-engine injector tester and cleaning solution. It’s particularly useful for users who want a multi-mode pulse generator, a broad range of adapter sizes including BMW/Audi compatibility, and built-in electrical protections for safer bench or in-vehicle testing. THIKPO also provides online technical support and a three-year warranty for added confidence.
