LS Ceramic leads

RACE SPARK PLUG WIRE SET – EXTREME 9000 CERAMIC BOOT – LS TERMINALS (LS1/LS2/LS3/LSA)

This custom-fit Extreme 9000 Race Spark Plug Wire Set with ceramic boots is designed specifically for GM LS1, LS2, LS3 & LSA engines

Built for high-performance and race applications, this wire set is ideal for LS engines running close-clearance headers, tight engine bays, or extreme under-bonnet temperatures.

If you’re constantly cooking plug leads or worried about misfires caused by heat damage during racing, this is the upgrade you need.

The Extreme 9000 wires feature ultra high-temperature 8mm double-silicone construction with a 500 ohms/ft ferro-spiral core designed for maximum performance and superior RFI/EMI suppression. The wire itself is rated to withstand peak temperatures of 600°F, while the ceramic boots handle temperatures up to 2,000°F.

Each lead is protected with high-temperature thermal sleeving (Inferno-style shielding) that increases heat resistance up to 1,200°F. The sleeving is secured with high-temp heat shrink to prevent movement under extreme conditions.

Stainless steel spark plug terminals ensure excellent energy delivery and long-term durability.

Perfect for:
• Track cars
• Drag builds
• Turbo / supercharged LS setups
• High compression race engines
• Tight header applications
