Description
This ignition wire set is configured for GM LS truck ignition applications with Straight spark plug boot configuration, durable boot materials, and suppression-focused construction for reliable street performance use.
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 black high-density silicone insulation and ceramic plug boot material 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 Straight 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.
