Product Details

Features

  • Bulk 8.5mm silicone-insulated wire for custom ignition wire builds
  • 500 Ohm resistance with spiral core for RFI suppression
  • Silicone insulation rated to 600°F for underhood heat resistance
  • Sold by the roll — boots & terminals not included, pair with a kit

Description

This bulk spark plug wire is sold by the roll at 8.5mm outside diameter and 100 feet in length, giving you the length needed to cut custom ignition wires for your specific cylinder routing. The spiral core construction provides RFI suppression to help reduce electrical interference, with 500 Ohm resistance — confirm this matches your ignition system's requirements, since some high-output or MSD-style systems specify different resistance ranges.

The silicone insulation is rated up to 600°F, supporting routing near warm engine-bay components when installed with proper clearance. This is raw wire only — boots and terminals are not included and are sold separately; pair this roll with a compatible boot and terminal kit (matching the 8.5mm wire diameter) to complete your ignition wire build.


Applications
Universal fit. Commonly used for street performance builds, restoration projects, and custom ignition-system assembly.

Installation
Sold as bulk wire by the roll — cut to length as needed for your specific cylinder routing. Boots and terminals are not included; confirm spark plug terminal style, coil or distributor configuration, and boot compatibility before ordering a matching kit.

Q&A

Does this come with boots and terminals?
No — this is bulk wire sold by the roll. Boots and terminals are sold separately; pair this with a compatible 8.5mm boot and terminal kit.

What resistance does this wire have?
500 Ohms. Confirm this matches your ignition system's requirements, since some high-output or MSD-style systems call for different resistance ranges.

How long is this roll?
100 feet, sold in bulk so you can cut wires to length for your specific cylinder routing.

What wire diameter is this?
8.5mm.

What's this wire rated for heat?
Silicone insulation rated up to 600°F, supporting routing near warm engine-bay components with proper clearance.

What boot kit should I pair with this wire?
Any 8.5mm-compatible boot and terminal kit — for example, TSP's 90° Spark Plug Boot for Female Cap Terminal Kit (SKU 85010), which matches this wire's diameter.
