distributor cap
Spark routing dome
A distributor cap is the cover on an automobile's distributor, which routes high-voltage current from the ignition coil to the spark plugs in the correct firing sequence.
The cap contains contact points for each cylinder's spark plug wire.
Distributor caps are found in older vehicles; most cars built since the 1990s use electronic ignition systems that eliminate the distributor entirely.
