Bosch Spark Plug Wire Cylinder

Bosch spark plug wire sets, also called ignition wire sets or spark plug cables, carry high-voltage current from the ignition coil or distributor to each spark plug. They help the engine get a consistent spark for smooth starts, steady idle and efficient combustion.

Key Features:

• Engineered to carry ignition voltage to the spark plugs with low resistance
• Insulated, multi-layer wire construction helps protect against heat, oil and abrasion in the engine bay
• Helps suppress radio frequency interference (RFI/EMI) to protect on-board electronics and radio reception
• Boots and terminals are made to seat securely on the plugs and coil or distributor towers
• Available in different cylinder configurations and wire styles, including standard and silicone-insulated sets

Bosch is a long-established name in ignition and electrical components. Replacing worn or cracked ignition wires can restore ignition performance and help prevent misfires, rough running and reduced fuel economy. Choose the variant that matches your engine's cylinder count and ignition design.
