Moroso BBC Under Header 90 Deg Plug Boots Non-HEI Sleeved Ultra Spark Plug Wire Set - Red

Moroso's BBC Under Header 90 Degree Plug Boots Non-HEI Sleeved Ultra Spark Plug Wire Set uses a 7mm silicone jacket over a suppressed-resistance spiral core. This construction helps manage heat and electrical interference, which is crucial for consistent ignition performance, especially in tight engine bays where headers can get very hot. The 90-degree boots are specifically designed to clear under-header installations, making them a practical choice for many big block Chevy applications.

These wires are built to handle the demands of a high-performance ignition system. The silicone jacket offers good resistance to heat and abrasion, while the suppressed-resistance core helps reduce radio frequency interference, ensuring a clean spark signal. This set is intended for non-HEI distributors, so be sure to check your distributor type before ordering. The red color adds a clean, finished look to your engine bay.
