Protect your ignition system from heat damage with this 8-pack of Spark Plug Heat Sleeves, engineered to safeguard spark plugs and wires from direct and radiant exhaust heat. Constructed from high-grade woven heat-resistant materials with a double-wall design, these sleeves help reduce misfires and prevent costly engine damage in high-performance setups.

Each sleeve is 6" (15.5cm) long and 1" (2.54cm) in diameter, making them ideal for tight engine bays, fuel lines near headers, or applications where space is limited. They can rest directly on exhaust manifolds or headers once fitted – no extra clearance is needed.
