MSD APS Replacement Starter Solenoid # MSD5087
These replacement starter solenoids from MSD are direct replacements for your MSD APS starter only. Your starter solenoid is a vital part of your vehicle that relays a large electric current to the starter motor, which in turn sets the engine in motion. If it fails, you’re not going anywhere. Don’t take a chance with an old, questionable, or malfunctioning starter solenoid that could leave you stranded–replace it with a new one from MSD Ignition.
