Product Details

Features

  • Ceramic plug boots rated for elevated underhood heat
  • 135° boot angle for clean coil pack routing
  • Full set of 8 plug wires, high-density silicone jacketing

Description

Built for GM LS/LT Series ignition applications, this ignition wire set combines 8.5mm wire construction, 135° spark plug boot configuration, and durable insulation for dependable spark delivery in properly matched applications.

Spark Delivery & Ignition Performance
The 8.5mm outside diameter to help transfer spark energy while reducing electrical interference in compatible ignition systems. Resistance is listed at 500 Ohms /Ft, which should be matched to the ignition setup.

Premium High-Density Silicone Heat Protection
The premium high-density silicone insulation help provide heat resistance and long-term durability. Premium high-density silicone with ceramic plug boots rated for elevated underhood heat supports routing near warm engine-bay components when installed with proper clearance.

Boot Configuration & Routing
The set uses 135° spark plug boot configuration to support clean routing between the plugs and distributor or coil packs.

Installation & System Matching
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.
