Delphi Distributor Rotor P/N:DC20025
Send spark to the right cylinder with the Delphi Distributor Rotor DC20022. Mounted on the distributor shaft, it spins beneath the cap and hands off the coil's high-voltage spark to each cap terminal in turn, so the correct spark plug fires in sequence. It's a direct-fit replacement across dozens of 1985–1995 GM applications, including the 1986–1995 Chevrolet Astro, 1985–1992 Chevrolet Camaro, 1988–1995 Chevrolet S10, 1986–1995 GMC Safari and 1985–1992 Pontiac Firebird — see the Buyer's Guide tab for the full vehicle and engine list.
A worn or carbon-tracked rotor can misroute spark and cause misfires, rough running or hard starting; if a failed rotor is the cause, this part replaces it. Backed by Delphi's OE ignition heritage.
