Distributor Cap Moroso Replacement

The Moroso Distributor Cap Replacement (Part No. 97855) is a heavy-duty HEI-style distributor cap engineered for circle track racing and high-performance engine applications. This non-vented cap features brass terminals with screw-down construction, providing secure electrical connections under demanding track conditions where vibration and temperature extremes can compromise standard ignition components.

The brass terminal design resists corrosion and electrical degradation, while the screw-down terminal system ensures positive contact that won't loosen during high-RPM operation or extended heat cycles. The gray, non-vented construction minimizes moisture intrusion and contaminants, critical factors in maintaining consistent spark delivery lap after lap. The cap's compact footprint (5.6 x 4.4 x 6 inches) and lightweight design (0.95 lbs) make it suitable for various engine bay configurations without adding unnecessary mass to the ignition system.

This replacement cap is designed for racers and engine builders who run Moroso circle track distributor systems and require OEM-equivalent performance. The HEI terminal configuration provides broad compatibility with standard ignition wires, while the screw-down terminals eliminate the loose-fitting terminal concerns that plague press-fit caps on vibration-prone vehicles. Whether rebuilding an existing ignition system or upgrading from stock components, this cap delivers the durability and electrical reliability expected in competitive motorsports.
