Bosch 021-905-295 B Ignition Condenser

The Bosch 021-905-295 B is a precision-engineered ignition condenser designed for points-type distributor ignition systems. This genuine Bosch component is a critical element in maintaining reliable engine performance on classic vehicles equipped with contact breaker point ignition.

Key Features:

• Reduces arcing across contact breaker points to minimize burning and pitting
• Extends ignition point service life by absorbing voltage spikes when points open
• Aids in rapid collapse of the ignition coil magnetic field for stronger spark generation
• Genuine Bosch OEM quality construction ensures reliable performance
• Square mounting configuration for side-mount distributor installation

This condenser (also known as a capacitor) connects across the distributor contact points and absorbs the sudden voltage change when the points open, preventing electrical arcing that would otherwise cause rapid deterioration of the points. By providing a controlled path for current flow during the switching cycle, it enables the ignition coil to generate the high voltage needed for consistent spark plug firing. Compatible with various Volkswagen and Porsche models equipped with standard or Bosch 009 distributors. Cross-reference numbers include 1-237-330-252 and 028851200745.
