Ford Small Block Race Fit 10.4mm 409 Series Spark Plug Wire Set with Over Valve Cover DSI Fitment (Available in 3 Colors)

Features & Benefits

10.4mm 409 Series wire sets provide continuous heat protection up to 600° Fahrenheit and 102,000 volts of dielectric strength making them a great choice for drag, circle track, off road and other high heat applications.

Race Fit wires arrive cut to exact length and fully terminated — boots and terminals installed on both ends, ready to drop straight in. Note that lengths are optimized for the chosen routing path; if you're running a fixed loom or an alternate wire path, fitment may vary. An extra-long coil wire is also included, one end fully prepped and the other left open so you can trim to length and finish with the boot and terminal to your high-performance coil of choice.
