Description
Aeroflow XPRO Ceramic GM LS Universal Spark Plug Lead Set – Black
Extreme-heat ceramic straight-boot ignition lead set for GM LS-series engines, offering maximum thermal protection and low-resistance spark delivery.
High-Performance Thermal Protection & Ignition Delivery
The Aeroflow XPRO Universal GM LS Ignition Lead Set (AF4038-32073C) is specifically engineered to overcome the high-heat challenges common in custom and motorsport LS engine bays. Featuring high-grade black ceramic spark plug boots capable of resisting extreme temperatures up to 1090°C (2000°F), these leads prevent boot melting, misfires, and premature insulation breakdown caused by tight header clearances and turbo exhaust manifolds.
Constructed around an 8.5mm (21/64″) spiral-wound copper conductor core wrapped in durable high-temperature silicone, this lead set offers exceptional EMI/RFI suppression with ultra-low resistance of 40-50 ohms per foot. Supplied with pre-fitted straight ceramic boots and loose LS coil boots/terminals, it allows custom tailoring for clean coil-relocation setups or custom header routing.
Key Features:
- ☑ 2000°F Ceramic Boots: Straight ceramic spark plug boots withstand extreme exhaust temperatures up to 1090°C.
- ☑ 8.5mm Spiral Core Wire: Low resistance (40–50 ohms/ft) with high EMI suppression for maximum spark energy.
- ☑ GM LS Fitment: Tailored for GM LS1, LS2, LS3, LS6, and LS7 V8 engines with coil relocation or custom lead routing.
- ☑ Cut-to-Length Flexibility: Includes 8 x 14″ (355mm) leads with pre-crimped straight ceramic boots and loose terminal/boot hardware.
- ☑ High-Temp Silicone Sleeve: Black high-dielectric outer jacket protects against oil, moisture, and engine bay abrasion.
