Moroso 51528 Ultra Series Spark Plug Wires Small Block Chevy Under Header HEI

The Moroso 51528 Ultra Series spark plug wire set is engineered specifically for Small Block Chevy applications requiring under-header routing. This premium ignition wire set features a durable black sleeved construction that protects against extreme heat and abrasion in tight engine compartments.

Key Features:

• Designed for Small Block Chevy engines with under valve cover and under header routing
• 90-degree plug boot ends for tight clearance applications and professional appearance
• HEI distributor compatible terminal configuration
• Ultra Series construction with high-temperature black protective sleeving
• Low-resistance conductors for maximum spark energy and performance
• Heat-resistant materials protect wires from header and exhaust temperatures

This wire set is ideal for performance street and racing applications where header clearance is critical. The under-header routing keeps wires away from hot exhaust components while maintaining proper spark delivery. The 90-degree boot design eliminates clearance issues with valve covers, headers, and other engine components common in modified Small Block Chevy engines.
