8.5mm Chevy Small Block Under Header Spark Plug Wire Set with 90° Plug Boots - Black

This ignition wire set is configured for Chevy small block ignition applications with 90° 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 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 90° spark plug boot configuration with 90° coil/distributor-end boot degree and Male or Female 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.
