Ultra 40 Plug Wire Set BBC Non-HEI Red

The Ultra 40 Plug Wire Set BBC Non-HEI in red by MOROSO is engineered for big-block Chevrolet engines that utilize traditional distributor systems. This product is ideal for serious engine builders and performance enthusiasts who need reliable ignition performance. Whether restoring a classic muscle car or preparing for a competition build, quality spark plug wires are essential for optimal engine response.

Featuring 8mm diameter cores, the Ultra 40 set is constructed with low-resistance materials that minimize voltage drop, ensuring consistent spark timing across all cylinders. The non-HEI configuration means these wires are designed to terminate in traditional terminal boots compatible with standard distributor caps, making installation straightforward without the need for additional modules or adapters. The durable polymer insulation resists heat, oil exposure, and mechanical damage, enhancing longevity.

Owners of BBC engines, particularly those with 454, 427, or 502 cid displacement, will appreciate the purpose-engineered wire geometry that allows for clean routing around engine components. This set is particularly beneficial for pre-1975 big-blocks and many street/strip builds that utilize vintage ignition systems. With red color-coded jackets, these wires also provide excellent visibility for maintenance and routing verification.
