Bosch 09743 Premium Spark Plug Wire Set

The Bosch 09743 Premium Spark Plug Wire Set is a direct-fit ignition wire set engineered to restore reliable, high-voltage spark delivery to your engine. Built using the same state-of-the-art manufacturing technology Bosch applies to original equipment ignition systems, this wire set meets and often exceeds the performance of the OE wires it replaces.

Key Features:

• Stainless Steel Mag Winding: Delivers maximum voltage to the spark plug for a hotter, more powerful, and longer-duration spark — reducing the chance of misfire and eliminating radio frequency interference (RFI)
• 100% Pure Silicone Jacket: Resists oil penetration and extreme heat for lifetime protection against wire set failure
• EPDM Inner Insulation: Prevents power-robbing voltage leaks for consistent ignition performance
• Snap-Lock Terminals / OEM-Style Connectors: Tightly crimped to the connectors to exceed OEM standards, ensuring worry-free installation and re-installation
• OE-Grade Quality Control: Every component — including boots and connectors — is held to the same exacting standards as Bosch original equipment parts

The Bosch 09743 spark plug wire set is backed by a no-hassle lifetime guarantee, making it a dependable choice for restoring factory-level ignition performance. Compatible with a wide range of domestic and import passenger car and light truck applications.
