Description
Spark plug boots are a critical component in any ignition system—they protect your spark plug wires from heat damage and electrical arcing that can degrade performance and cause misfires. MSD’s 90-degree silicone boots are engineered to withstand extreme underhood temperatures while maintaining a secure connection, making them essential for reliable spark delivery in high-performance applications. The 90-degree configuration lets you route wires through tight engine bays without kinking or stress, while the included pair ensures you can address multiple cylinders in one purchase.
