Bosch 901-110-271-00 Mechanical Fuel Injector for Porsche 911

The Bosch 901-110-271-00 is a precision-engineered mechanical fuel injector designed for Porsche 911 models equipped with Bosch mechanical fuel injection (MFI) systems. This injector was originally used in 1965-1973 Porsche 911E and 911S models that featured the sophisticated Bosch PE pump-based mechanical injection system.

Key Features:

• Genuine Bosch OEM quality construction for reliable performance
• Designed for mechanical fuel injection systems operating at approximately 250 psi
• Provides precisely measured and timed fuel delivery to intake ports
• Compatible with Bosch mechanical injection pump systems
• Essential component for maintaining proper fuel atomization and engine performance

The mechanical fuel injection system used in early 911 models was derived from Bosch diesel injection technology and represented a significant advancement over carburetor systems. Each injector delivers a timed pulse of fuel once every two engine revolutions, coordinated with the specific cylinder's intake valve event. When properly maintained, this system provides superior throttle response and fuel delivery compared to carburetors.

Technical Notes:

• Part of the Bosch PE (pump element) mechanical injection system
• Works in conjunction with six-piston mechanical injection pump
• May also be identified by Bosch number EP/DCC45R3
• Cross-reference numbers: 90111027100, 901.110.271.00

This injector is a critical replacement component for maintaining the performance and reliability of classic Porsche 911 models with mechanical fuel injection. Worn or malfunctioning injectors can lead to rough idle, poor throttle response, and decreased fuel economy.
