Bosch 09356 Premium Spark Plug Wire Set - High Performance Ignition Wires for Cars, Trucks & SUVs - Perfect for Engine Tune-Ups & Performance Upgrades

State-of-the-art manufacturing technology and quality control systems ensure that Bosch Premium Wire Sets meet, and often exceed, the performance of the original equipment wire sets that they replace. That's true for all of the components, including the wire set boots and connectors.

Stainless steel Mag winding delivers maximum voltage to the spark plug for a hotter, more powerful, and longer spark resulting in optimum engine performance while reducing the chance for misfire, and eliminating radio static

100% Pure silicone jacket resists oil penetration, for lifetime protection against wire set failure

EPDM inner insulation stops power-robbing voltage leaks

"Snap lock" terminals or OEM style connectors ensures that wires are tightly crimped to the connectors to exceed OEM standards, providing worry-free installation and re-installation

Backed by a "no hassle" lifetime guarantee
