Carbon buildup often seizes nozzle caps, making removal difficult. The G4-84 Multifunctional Tool uses a collet/chuck clamping system to grip the cap evenly around its circumference. This prevents the "ovalization" or crushing that happens with standard wrenches.




Features & Advantages:
Universal Fit: Adjustable clamping range (approx 11mm-19mm) covers most passenger car and truck injectors.
Non-Slip: The tighter you turn, the harder it grips.
Damage Prevention: Saves the nozzle cap for reuse.
Application Scenarios: Removing seized caps from high-mileage Bosch, Denso, or Delphi injectors.
