Distributor cap replacement runs $80 to $200 installed. Modern vehicles do not have distributors - this job applies almost exclusively to cars built before 1998 and some commercial vans into the early 2000s. Replace the rotor at the same time.
Most drivers pay $110 to $160 with cap, rotor, and labor at an independent shop.
Brass-terminal caps last longer than aluminum.
Always done at the same time, $8-$25 in parts.
Often replaced together, $30-$120 for a set.
V6 and V8 distributors take longer to access.
Older GM HEI uses larger caps that cost more.
Few modern shops stock these - specialty or classic-car shops only.

If it was built before 1998, probably yes. After 1998, almost all cars use coil-on-plug or coil-pack ignition with no distributor.
Every 30,000-50,000 miles on a daily-driven car. Inspect at each tuneup for cracks, carbon tracks, and corroded terminals.
If the wires are more than 50,000 miles old or show cracks, yes. A new cap with old corroded wires is a half-job.
A black burned line inside the cap where spark has been jumping to the wrong terminal. The cap is done - replace it.
Moisture in a cracked cap or worn wires shorts the spark to ground. Replace the cap, rotor, and wires.
For light corrosion on the terminals, light sanding helps temporarily. Any cracks, carbon tracks, or loose terminals mean replacement.
