Chevii/Nova 68-74 N/Hei

The Taylor/Vertex Spiro-Pro spark plug wire set for Chevrolet Nova and small block Chevy engines is a complete ignition wire solution designed for high-performance and stock engine applications. This eight-millimeter spiral-core wire kit delivers reliable spark delivery with blue jackets and 90-degree plug boots that accommodate socket-style connections, making installation straightforward and ensuring proper cylinder firing across all engine configurations.

The spiral-core construction minimizes electromagnetic interference and cross-firing, critical for maintaining clean ignition timing, especially on small block Chevy platforms where tight plug spacing demands precision wire routing. The eight-millimeter diameter provides the optimal balance between resistance and flexibility, allowing these wires to navigate the engine bay without kinking or crimping that would degrade conductivity. The 90-degree boot design prevents wire separation under vibration and thermal cycling while the socket connectors ensure a secure fit at the distributor cap.

This kit serves both restoration and performance builds on first and second-generation Chevy Nova models, as well as any small block Chevy engine swap or rebuild. The blue jackets provide clear visibility during engine diagnostics and maintenance. Whether you're tuning carbureted or early fuel-injected small blocks, this wire set maintains the voltage delivery necessary for consistent combustion across a range of RPM and load conditions. The complete kit simplifies wiring by eliminating the need for individual wire sourcing and ensures all eight cylinders receive matched-length, matched-resistance spark delivery.
