Emissions
This part is legal for sale or use on Emissions Controlled Vehicles, Uncontrolled (Non-Emissions Controlled) Vehicles, and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations.
See Emissions DetailsOur Universal spark plug wire sets come with the spark plug terminal and boot installed with the other end open. Distributor cap boots and terminals are included so you can cut the wire to the desired length, then install the terminal with the supplied Mini-Stripper-Crimper. It's a little more work, but in the end it will be worth it.
Routing spark plug wires is an art form. It takes patience and time to route your wires away from the headers, through separators and to the distributor cap. Some wire sets fit perfect, but a lot of people want to build their own so they can route them exactly how they see fit.
Features:
- Extra long 8.5mm wire so you can cut to your desired length
- Includes Mini-Stripper-Crimper
- Includes both socket-style and spark plug-style boots and terminals
