Sierra 18-8829-1 Spark Plug Wire Set, 5.7L 8-Cylinder Delco HVS Ignition, 2005 & Up

The Sierra 18-8829-1 is a MAGFORCE spark plug wire set built for 5.7L 8-cylinder marine engines equipped with Delco HVS ignition, 2005 and up. Sierra designed the MAGFORCE line to be "electronics friendly," shielding sensitive electronic devices and electronic engine controls from radio frequency interference (RFI) and electromagnetic interference (EMI) while still delivering maximum voltage to each cylinder. The set includes one 21 inch coil wire along with spark plug wires supplied in three paired lengths (225 inches, 28 inches, and 32 inches) to route correctly around the engine, and terminates in a screw-down cap at the distributor.

Construction features moisture-proof, molded distributor insulators that keep water and humidity out of the connection points, plus a high-quality conductive center carrier reinforcement that maintains conductor integrity over time. The core is Mag/Wire wound to deliver maximum voltage output without generating RFI or EMI that could interfere with onboard electronics. Each set uses an exact-fit design engineered for straightforward installation and dependable, trouble-free service in the marine environment. This wire set is intended specifically for 5.7L, 8-cylinder engines running Delco HVS ignition, 2005 and up.
