Product Details

Features

  • 8.5 mm wire construction with spiral wound helps support reliable spark transfer and stable ignition-system operation.
  • Premium high-density silicone rated for up to 600°f helps protect against heat exposure while maintaining flexibility for clean wire routing.
  • 135° spark plug boot configuration supports application-specific plug clearance and routing; coil/distributor boot details should be verified before installation.
  • Gm ls/lt series ignition applications fitment with common use in Chevrolet Silverado, GMC Sierra, Chevrolet Camaro; verify plug ends, coil layout, and wire length before installation.

Description

For ignition-system upgrades and replacement service, this wire set pairs 8.5 mm cable construction with application-specific boot geometry for clean fitment and dependable spark transfer.

Spark Delivery & Ignition Performance
The 8.5 mm outside diameter uses spiral wound core material with radio frequency interference noise suppression to help transfer spark energy while reducing electrical interference in compatible ignition systems. Resistance is listed at 500 Ohms, which should be matched to the ignition setup.

Premium High-Density Silicone Heat Protection
The red high-density silicone insulation and silicone plug boot material help provide heat resistance and long-term durability. Premium high-density silicone rated for up to 600°f supports routing near warm engine-bay components when installed with proper clearance.

Boot Configuration & Routing
The set uses 135° spark plug boot configuration with 135° coil/distributor-end boot degree and Coil Pack terminal compatibility to support clean routing between the plugs and distributor or coil packs. Wire separators included: Yes.

Installation & System Matching
Fitment type is listed as Universal. Confirm spark plug terminal style, coil or distributor configuration, cylinder routing order, separator placement, and heat clearance before installation. LS and LT applications should be matched by engine family and coil location rather than engine-code wording.
