Frequently Asked Questions

How much should I pay for this repair on a Chevy Silverado 1500?

A fair price at a reputable independent repair shop is approximately $231. Dealerships typically charge around $353 due to higher labor rates and OEM packaging markups.

How often should spark plugs be replaced?

Standard copper plugs require replacement every 30,000 miles; modern OEM Laser-Iridium or Platinum plugs last 80,000 to 100,000 miles.

What happens if you ignore old spark plugs?

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

Why is spark plug labor high on some V6 engines?

Transverse V6 engines often have rear bank cylinders hidden underneath the aluminum intake manifold plenum, requiring manifold removal.
