VEMO 000-158-39-90 Ignition Contact Breaker Point Set

The VEMO 000-158-39-90 Ignition Contact Set, also known as breaker points, is a precision electrical switching component designed for classic distributor-based ignition systems. This aftermarket replacement part meets OEM specifications and replaces Mercedes-Benz part number 000 158 39 90.

Function and Purpose:

Contact breaker points serve as the switching mechanism in the primary ignition circuit, opening and closing to interrupt current flow through the ignition coil. When the distributor cam forces the points to open, the primary circuit breaks, causing the magnetic field in the ignition coil to collapse rapidly and generate the high-voltage spark needed to ignite the air-fuel mixture in the combustion chamber. The points are actuated by an engine-driven cam inside the distributor, with precise timing critical to optimal engine performance.

Key Features:

• Direct replacement for Mercedes-Benz OEM part number 000 158 39 90
• Precision-engineered contact surfaces for reliable electrical switching
• Spring-loaded design ensures proper contact closure and opening
• Manufactured by VEMO, a trusted aftermarket specialist in electrical components and sensors
