Bosch Distributor Cap

The Bosch Distributor Cap is an ignition distributor cap for distributor-equipped engines. It sits on top of the distributor housing and sends high-voltage current from the ignition coil to each spark plug wire in the correct firing order. Depending on the application, it may also be called a distributor cover or ignition distributor cap.

Key Features:

• Distributes ignition coil voltage to each cylinder in firing order
• Internal terminals are built to resist corrosion and electrical wear
• Insulating housing is designed to withstand engine heat, vibration and moisture
• Engineered to meet or exceed original equipment specifications
• Part of the Bosch ignition range, backed by Bosch's experience as an OE supplier

Cracks, carbon tracking or worn terminals in a distributor cap can cause misfires, rough idle, hard starting and poor fuel economy. A quality replacement helps restore smooth, reliable ignition performance. It is often replaced together with the rotor and ignition wires as part of a tune-up.
