Blue Distributor Cap - 1968-79 - Vacuum Advance, 009 Distibutors

This aftermarket clear blue distributor cap is a unique upgrade for classic VAG ignition systems, combining reliable performance with a striking visual feature. Manufactured from transparent blue material, this 65mm cap allows you to see the spark activity inside the distributor while the engine is running—ideal for diagnostics, tuning, or simply adding a custom look to your engine bay.

Designed for use on 1300cc to 1600cc aircooled engines fitted with vacuum advance or 009-style distributors, this cap fits securely to the distributor body and performs the same essential role as a standard cap. As the rotor arm spins inside, it distributes high voltage from the ignition coil to each spark plug lead in the correct firing order. The transparent housing allows you to visually confirm spark delivery and identify issues such as weak spark, crossfire or tracking.

Constructed from durable insulating material, this cap provides good resistance to heat and electrical interference while offering a custom appearance. Perfect for show cars, engine builds or anyone wanting a more interactive and visual ignition system.

Always check your distributor type and cap diameter before ordering. For best results, we recommend replacing the rotor arm, contact points, condenser, spark plug leads and spark plugs at the same time.
