Distributor caps and rotors are some of those parts that need replacement on a regular basis over the life of your vehicle. You’ll want to be picky about the ignition components you choose, because everything about your vehicle’s performance depends on that little spark of electricity. The MSD Distributor Cap is made by people who understand high performance and dedicate their working lives to the design and manufacture of high quality racing-level components. MSD Distributor Caps are optimized for top performance under a wide range of driving conditions, able to stand up to anything on the speedway or the highway. The MSD Distributor Cap is five inches in diameter, and terminals are spaced two inches apart – eliminating the “scatter” effect that sucks power out of your engine. A deep skirt and thick vanes keep air circulating, so you won’t experience the kind of ionization problems that cheap OEM components made in China and Mexico can cause. The entire body of the device is made with Rynite, a material made by DuPont, that easily stands up to engine heat. Whether you need to recap your stock distributor, replacing the OEM unit, or installing a high-performance Pro Mag distributor, MSD is the name.
