MSD 90° Spark Plug Boots Gray Silicone 50 Pack 34514

MSD spark plug boots are essential wear items in any high-performance ignition system. When silicone boots degrade or crack, they allow spark leakage that directly impacts combustion efficiency and engine reliability. This 50-pack of 90° boots ensures you have spares on hand for multiple vehicles or long-term maintenance needs, eliminating downtime between races or track days.

The 90-degree angle design accommodates tight engine bay layouts where straight boots won't fit, while the gray silicone compound resists heat cycling and ozone exposure better than inferior alternatives. Compatible with 8.5mm spark plug wires, these boots maintain consistent spark delivery across all cylinder banks—critical for balanced fuel mixture and peak horsepower.
