Our Spark Plug Replacement Process

At RG Brakes & Alignment, our process ensures your vehicle gets the care it deserves:

1. Inspect the ignition system – including spark plugs, ignition coils, coil boots and wires (if applicable)

3. Install new OEM spark plugs – matched exactly to your engine’s specs

5. Torque to manufacturer specs – ensuring proper combustion and long plug life

2. Remove old spark plugs carefully – without damaging threads or components

4. Use dielectric grease and anti-seize (as needed) – to ensure long-lasting performance

6. Test the engine – to verify performance and ensure the misfire is gone

We service all vehicle types – domestic, Japanese and European. No matter if you drive a Ford F-150, Honda Accord, Toyota Camry, Chevy Silverado, BMW 3 Series or Hyundai Sonata – we’ve got you covered.

What Spark Plugs Do and Why They Matter

Spark plugs ignite the air-fuel mixture inside your engine cylinders. This ignition is what powers your engine’s pistons and ultimately moves your vehicle.

Over time, spark plugs wear down or become coated in carbon deposits. When that happens, combustion becomes incomplete or inconsistent, which can lead to symptoms like:

  • Engine misfires
  • Rough idling
  • Poor acceleration
  • Hard starts
  • Reduced fuel economy
  • Check engine lights

Failing to replace spark plugs on time can damage your catalytic converter and reduce overall engine life.

When Should Spark Plugs Be Replaced?

Most manufacturers recommend changing spark plugs every 30,000 to 100,000 miles, depending on the type:

  • Copper spark plugs: ~30,000 miles
  • Platinum or Iridium spark plugs: 60,000–100,000+ miles

Common Signs You Need New Spark Plugs:

  • Hesitation when accelerating
  • Increased fuel usage
  • Engine feels rough at idle or shakes
  • Check engine light, especially codes like P0301–P0308
  • Trouble starting in cold weather

If you’re experiencing any of these issues, it’s time to schedule service.

Benefits of Replacing Spark Plugs

  • Better fuel economy
  • Faster starts and smoother idling
  • More responsive acceleration
  • Reduced engine misfires
  • Lower emissions
  • Prevention of damage to ignition coils and catalytic converters

Frequently Asked Questions

How much does it cost to replace spark plugs?

Cost depends on how many cylinders your engine has, whether coils or wires need to be removed, and the plug type (iridium, platinum, etc.) We’ll give you a quote before starting work.

Can I drive with bad spark plugs?

For a short time, yes but it can lead to misfires, poor performance and even damage to your catalytic converter or ignition coils if left unresolved.

Will replacing spark plugs fix my check engine light?

If the misfire codes (P030X) are caused by worn or fouled spark plugs, then yes, replacing them will usually clear the light. We always run diagnostics first to confirm.

Do you check coils and wires too?

Yes. During spark plug service, we inspect ignition coils and boots for signs of wear, cracks or electrical faults. If anything else needs replacement, we’ll let you know before proceeding.

How long does spark plug replacement take?

Most 4-cylinder or 6-cylinder vehicles can be done in under 2 hours. Some V8 engines or vehicles with hard-to-reach plugs may take longer. We’ll give you a clear estimate of time and cost upfront.
