FixFord F-150 — Spark Plugs Replacement Cost
What owners actually paid
The shaded middle is where half of all these repairs landed: $229 – $606. A quote inside that band is normal. Cheaper or pricier isn't automatically wrong — but it's worth asking why.
Real repair reports
These reports are a recent sample of real, paid Ford F-150 spark plug replacement visits — quoted the way the owner and the technician actually said it.
Car owners said
“Install coil and spark plug on cylinder 2”
“Called-----check eng. light on and running rough”
“Diagnose and repair misfire-replace #4 cylinder spark plug”
“Check tightness of customer installed spark plugs”
“Lack of power on acceleration”
“Misfire, check plugs and wires”
What the technician found
“Customer requested replace cylinder 2 ignition coil and spark plug.”
“Misfire cylinder 6. inspect plugs and coils. found plugs severely worn. r/r all spark plugs. verified proper operation”
“Spit out cylinder 6 spark plug, may have already been repaired. advise Hole looked good repaired.”
“Removed engine cover and unplugged ignition coils and high pressure fuel pump to gain access the spark plugs. Removed and replaced spark plugs and coil boots. Installed all parts removed for repair. Test ok.”
“#2,3,&6 spark plugs cracked. ceramic loose in spark plug tube. replaced plugs and no misfires. **do not put anti-seize on spark plugs.”
“Tune up - spark plugs and connectors labor to remove and replace spark plugs, check ignition coils, use die electric grease on coil boots, clean mass airflow sensor, check system for codes. all checks good”
What this repair is
Spark plugs ignite the fuel in each cylinder. Worn plugs cause rough running, misfires, poor fuel economy, and eventually a flashing check-engine light. Modern plugs last 60k–100k miles; the price is mostly labor, which varies hugely by how buried the plugs are on your engine.
Is your quote fair?
If your quote lands between $229 and $606, it's inside the range where half of all real Ford F-150 repairs of this kind land — and the typical job takes about 2.5 hours of labor. Quotes well below aren't automatically good news (economy parts, or related work skipped) and quotes above aren't automatically gouging (trim variants, premium parts, seized hardware) — but both ends deserve questions.
