Frequently Asked Questions
How much should I pay for this repair on a Ford F-150?
A fair price at a reputable independent repair shop is approximately $241. Dealerships typically charge around $368 due to higher labor rates and OEM packaging markups.

Worn electrodes create wide gaps that overwork ignition coils, causing coil burnout and unburned fuel that overheats the catalytic converter.
