Aldon Automotive Performance Distributors - BMC B Series 101BY1S With Contact Breaker Ignition

Aldon Automotive Performance Distributors for BMC B Series Engines - Enhance Your Engine's Power and Driveability.

With performance upgrades like tuned camshafts and twin side-draught carburettors, the stock distributor may no longer provide the correct ignition advance curve necessary for optimal engine performance. This mismatch can result in power loss and decreased drivability. Aldon Performance Distributors are based on new Lucas or Bosch units and have been dynamically tested to offer the ideal ignition curve tailored to various engine tunes. Many models are available with a mechanical advance option suitable for engines using twin side-draught carburettors.

Key Features:

• Customised ignition advance curves for improved power output and drivability
• Option for mechanical advance on specific distributor versions
• Suitable for BMC 'B' Series 101BY1S, 101BY2, 101BR1, and 101BR1S distributors
• Fitness options available for a range of popular camshaft upgrades
• Electronic ignition (Ignitor) upgrade for enhanced reliability and consistent ignition trigger
