Moroso Ultra 40 8.65mm Plug Wire Set Blue for Small Block Chevy HEI

The Moroso Ultra 40 8.65mm Plug Wire Set is engineered specifically for Small Block Chevy engines equipped with High Energy Ignition (HEI) systems. This wire set enhances the performance and reliability of your ignition system, ensuring that your engine performs at its best. The use of advanced materials and construction techniques guarantees superior conductivity and resistance to heat and abrasion, making it a dependable choice for both street and race applications.

These plug wires stand out due to their unique blend of materials, which include a high-temperature silicone outer jacket that protects against heat and chemicals. The 8.65mm diameter is optimized for maximum spark delivery while providing a robust barrier against electromagnetic interference. This is crucial for maintaining the efficiency of your ignition system, especially under high-stress conditions, such as during racing or heavy towing.

Additionally, the Ultra 40 wires are designed with performance in mind, featuring a spiral-wound conductor that ensures low resistance for optimum voltage transmission. This means you get a stronger spark at the plug, resulting in improved fuel combustion and overall engine performance. The blue color adds a visual appeal that can enhance the look of your engine bay.
