• Blue high-temperature silicone outer jacket rated for temperatures above 250 °C (482 °F)
• EPDM/silicone inner insulation for excellent dielectric strength
• 7 mm insulation outside diameter
• OE-quality or better silicone spark plug and distributor boots, glued to the cable with silicone sealer for a watertight seal
• Stainless steel terminals with serrated crimps that grip the cable jacket and inner insulation for strong terminal retention
• Locking, corrosion-resistant spring clip for a secure spark plug terminal connection
