Key Features:

• 8mm, 800 Ohm Spiral Core Design — Strategically wound 304 stainless steel alloy conductor delivers high, even spark energy levels for consistent ignition performance
• DuPont™ Kevlar® Core — Up to four times stronger than traditional aramid fiber cores while using less material, resulting in a smaller core diameter
• Extra-Thick EPDM Insulation Layer — The reduced core diameter allows for a larger EPDM insulation layer, providing greater dielectric strength and protection
• 8mm Silicone Jacket — Resists heat and chafing for long-lasting durability in high-heat engine environments
• Silicone Plug Boots — Withstand temperatures up to 600°F, ensuring a secure, heat-resistant connection at the plug
