Bosch Premium Spark Plug Wire Set

Bosch Premium Spark Plug Wire Sets are replacement ignition wires. They carry high-voltage current from the ignition coil or distributor to each spark plug. A strong, consistent spark supports smooth starts, steady idle and dependable engine performance. Each set is built to meet or exceed the performance of the original equipment (OE) wires it replaces.

Key Features:

• Stainless steel mag-wound conductor: Delivers maximum voltage to the spark plug for a hotter, longer spark. It also reduces the chance of misfire and helps eliminate radio static (RFI).
• Silicone jacket: Resists oil penetration and heat, which helps protect the wire set from failure.
• EPDM inner insulation: Helps stop power-robbing voltage leaks.
• Snap-lock terminals or OEM-style connectors: Crimped tightly to the wire for secure installation and re-installation.
• Quality-controlled boots and connectors: Manufactured with the same quality standards as the wires.
• Lifetime guarantee: Backed by Bosch.

Bosch Premium spark plug wire sets are available for a wide range of foreign and domestic cars, vans and light trucks. Choose the correct part number for your engine from the options on this page.
