Overview

The ACDelco 618W spark plug wire set is an Original Equipment (OE) replacement designed for specific Chevrolet Corvette models from 1985-1991. These wire sets include insulating material, connectors, and boots to effectively transfer high-voltage pulses from the voltage source to the vehicle's spark plugs. Constructed with a silicone insulation material and silicone-angled boots at the distributor coil end, these wires are built for durability and proper fit within the engine compartment.

Each wire features a solid boot type and a snap lock terminal at both the coil and spark plug ends, ensuring a secure connection. The black insulation color and silicone spark plug boot material contribute to their robust design.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
