Bosch Piezo Injector Valve – ALT 116 / ALT 117

The Bosch Piezo Injector Valve F00GX17005, available as ALT116 and ALT117, is a precision diesel injector spare part engineered for Bosch 0 445 116 and 0 445 117 series common rail injectors. This injector control valve plays a critical role in regulating internal fuel pressure within piezo-type Bosch injectors, directly controlling the injection timing and fuel quantity delivered to the combustion chamber. The ALT116 and ALT117 diesel injector valves are manufactured to strict OEM dimensional standards, ensuring compatibility with original Bosch common rail injector systems. Their precision construction allows reliable operation under the extreme pressure and temperature conditions typical of modern common rail diesel fuel injection systems. As a key diesel injector spare part, this valve maintains accurate fuel metering and injection control, contributing to efficient combustion, stable engine performance, and reduced exhaust emissions. The valve is compatible with a wide range of European passenger cars and light commercial vehicles equipped with Bosch piezo injection technology. Bosch OEM references include F00VX17005 and F00GX17005, with compatibility covering injector numbers 0445116019 and 0445117046 series.
