Ultra 6AL Plus Ignition Box - Red Finish

The Ultra 6AL Plus Ignition Box - Red Finish is a professional-grade ignition control module engineered for street and strip applications where reliable spark delivery and advanced timing control are essential. Built by MSD IGNITION, a leader in high-performance electrical systems, this capacitive-discharge ignition unit provides the precision spark management needed for various engine configurations, including carbureted small-block Chevys and turbocharged LS platforms.

This ignition box generates a significantly hotter spark than factory distributors or basic aftermarket boxes through MSD's proven capacitive-discharge technology, which stores and releases energy at precisely the right moment for optimal combustion. The unit features adjustable timing curve control, allowing tuners and owners to customize the advance characteristics their engine requires at idle, cruise, and wide-open throttle. Its compact, potted epoxy core protects internal circuitry from vibration, heat, and moisture common in engine bays, while the bright red powder-coat finish offers visual identification and corrosion resistance.

The Ultra 6AL Plus Ignition Box is ideal for serious enthusiasts and builders who demand consistent cold starts, improved fuel economy, and maximum spark intensity across the entire RPM band. Its compact footprint (10.3 x 3.25 x 10.9 inches) and modest weight of 2.89 lbs make it easy to mount on the firewall, inside the cabin, or under the dash without compromising underhood real estate.
