Moroso Ultra 350 8mm Red Multi-Angle Spark Plug Wire Set for GM BBC 366-454 (HEI-Style w/o Coil In Cap) 52039
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits GM Big Block Chevy (BBC) 366, 396, 402, 427, and 454 engines equipped with HEI-style distributors (without coil-in-cap).
The Moroso Ultra 350 Spark Plug Wire Set is engineered for high-performance street and racing applications where ignition reliability is critical. These 8mm wires feature a high-dielectric silicone jacket that resists heat, oil, and chemicals, ensuring consistent voltage delivery to the plugs. The multi-angle boots provide the necessary flexibility to clear exhaust headers and tight engine bay clearances, solving common routing issues on Big Block platforms. This set is designed specifically for external coil HEI setups, providing a secure, snap-lock fit at the distributor cap.
- 8mm wire diameter with a durable red silicone insulation jacket
- Multi-angle spark plug boots for optimized routing and header clearance
- Compatible with HEI-style distributor terminals (external coil applications)
- Pre-terminated for straightforward installation on GM Big Block V8 engines
- Manufacturer Part Number: 52039
