Govoni
Govoni makes special tools for engine and suspension repair. Autotools stocks Govoni glow plug extraction kits, injector seat taps, spring compressors, a ball joint puller and a 700 bar hydraulic pump.
Govoni tools are for workshops that take on the hard jobs: a seized or snapped glow plug, a stuck injector or a suspension spring swap.
For glow plug kits, check the thread size, such as M8x1 or M10, and the engine the kit is made for. Broken plugs have their own modular extraction kit.
