Product Details

The ThunderCore PRO line focuses on ignition wire construction that supports stable spark delivery under demanding underhood conditions. Part number 924-1427 uses heat-resistant silicone boots and tips, stainless steel terminals, and tubes to support secure connections at the plug and distributor ends. Walker 924-1427 is a direct-fit ignition wire set for service work on Chevrolet P30, R30, V30, C20, C20 Suburban, C30, K20 Suburban, K30, R3500, V3500, and GMC P3500, R3500, V3500, C2500, C2500 Suburban, C3500, and K3500 applications listed below.

This part cross-references DENSO Auto Parts (e.g., 671-8034, 4085) for the same application.

What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak spark transfer
• Intermittent ignition performance from cracked boots or terminals
• Voltage leakage at the wire ends in high-heat environments
• Service replacement for aging Chevrolet and GMC ignition wire sets

Installation Notes

Verify engine and exhaust-manifold configuration before ordering. Some 1985-1986 Chevrolet and GMC applications are listed only for vehicles equipped with a stainless steel exhaust manifold. Route each wire to match the original layout, and apply the included dielectric grease at the boots during installation.
