RODA SERVICE
Replace Spark Plugs
Spark plugs are small but vital — they ignite the fuel-and-air mixture that powers your engine. Over time, plugs wear down or foul, causing rough starts, poor fuel economy, or misfires.

Why Estimates May Vary
$225 - $360 with RodaCare
$250 - $400
Our goal is full transparency — pricing may vary based on:
- Cylinder count (vehicles with 6+ cylinders cost closer to $500-$1000)
- Vehicle make and engine type (some engines require more plugs or complex access)
- Plug type (standard, platinum, or iridium plugs have different lifespans and costs)
- Additional labor (removing covers or intake components can increase service time)
We’ll always provide an exact quote after inspection — no surprises, ever.
When You Need This
Worn spark plugs can reduce your engine’s performance, efficiency, and reliability. Here’s when to schedule a replacement:
Hard Starts or Rough Idling
Misfiring plugs make your engine sound uneven or cause it to shake when idling.
Decreased Fuel Economy
Worn plugs cause incomplete combustion, leading to higher fuel consumption.
Sluggish Acceleration or Misfires
Hesitation or jerky acceleration often points to plugs that can’t fire properly.
Scheduled Maintenance
Most spark plugs last 30,000–100,000 miles, depending on material and driving conditions. Replacing them on time prevents ignition problems.
