Black Wire Retainer MSD 74093, Replacement, Pro Cap, PN 7445/PN 7455

MSD was the first company to develop and offer the capacitive discharge ignition and multiple sparking for engines.

The line of MSD 6-Series Ignitions are the most popular aftermarket ignitions in the world due to race-proven performance on the track and reliability on the street!

Racers never stop experimenting as they search for every way to wring out more power or handling performance to gain an edge over the competition.

The team at MSD is no different as we strive to deliver the products needed to meet performance goals.

We continue to innovate and invent components and technology that deliver reliability and performance with products that are easy to use and install.

Over the course of 40-plus years, MSD Performance has been driving the development of innovative components that helped shape the way cars race and perform.

From super speedways to road courses, land speed racing to top fuel dragsters, and of course traditional hot rods, MSD has provided the components to fire nearly anything in motorsports.

Early on, MSD focused squarely on ignition systems with revolutionary products like the multiple sparking CD ignition, timing and rev controls, billet aluminum distributors, and the Pro-Mag, an incredible breakthrough in endurance and power.

Today MSD is developing electronics for the entire powertrain.

The Atomic EFI systems for the LS engine platform and throttle body are now complemented with a transmission controller.

Our DynaForce Starters and Alternators ensure that the engine cranks over to fire up and the Alternators keep it charged.

MSD is poised to deliver components that work and communicate together to provide value and performance.
