Premium Heat-Resistant Spark Plug Wire Boots
High-temperature silicone construction withstands extreme engine heat up to 500°F (260°C) for reliable insulation. Precision-molded ribbed design ensures airtight sealing against moisture and debris. Reinforced fiberglass core prevents cracking under vibration for extended durability.
Direct-fit sleeves compatible with most gasoline/Diesel engines – ideal for turbocharged or high-performance vehicles. Easy slip-on installation requires no tools – simply slide over existing spark plug wires.
Ultra-thin 3mm wall thickness maintains flexibility while adding critical thermal protection. Flame-retardant material meets SAE J2031 standards for automotive safety.
Perfect for track days, off-roading, or daily drivers – prevents misfires caused by heat soak. Sold in bulk packs for commercial repair shops or fleet maintenance.
Wholesale pricing available for distributors – global shipping with guaranteed lowest rates. Custom OEM solutions offered for large-volume buyers.
