Spark Plugs Replacement in San Carlos, CA

our vehicle will need regular spark plugs replacement throughout its lifetime. Spark plugs generate the sparks that ignite air-fuel mixture that powers your vehicle’s engine. Spark plugs lifespan can vary from 30,000 miles to 90,000 miles – it depends on the materials used in their manufacture. At Toole’s Garage in San Carlos we offer complete car care, including spark plugs replacement.


Signs of failing spark plugs can include misfire, or check engine light coming on. When you bring your vehicle to our San Carlos auto repair shop, we will perform professional engine and starting/charging/electrical system diagnostics to determine the root cause of the problem. If spark plugs are found to be at fault, we can perform spark plugs replacement and have your car ready for the road, usually the same day.


Here are additional symptoms that can indicate spark plugs problems. It’s time to visit your friendly mechanic if your vehicle exhibits any of these issues – even if it turns out that spark plugs are not at fault, it’s important to get your vehicle checked out by a professional:


  1. Decreased engine performance can be a symptom of failing spark plugs.
  2. Engine misfires can indicated failing spark plugs - this in turn will make the check engine light come “on”.
  3. Rattling noises can also occur when spark plugs are going bad.


When you notice any of the above symptoms, make an appointment to bring your vehicle to our San Carlos auto repair facility. If you remember when the spark plugs were last changed, let us know. But if you don’t, worry not, we will test the vehicle and get to the bottom of the problems. As mentioned previously, typically spark plugs replacement intervals are between 30,000 miles and 90,000 miles. If your vehicle has copper spark plugs, they are likely to need replacement within 30,000-40,000 miles. On the other hand, iridium spark plugs can last as long as 90,000 miles.

When you bring your vehicle to Toole’s Garage in San Carlos our nationally ASE certified technicians will inspect your vehicle, and we will let you know exactly what is needed to make it happy again – before we do any repairs. As a matter of fact, with every service or repair we offer free digital vehicle inspection, so that you are up-to-date on the overall condition of your vehicle. With all services and repairs, you can expect not only friendly customer service, but also:


  • 36 months / 36,000 miles nationwide warranty
  • Military and First Responder discounts
  • Free Digital Vehicle Inspection with service or repairs
  • In most cases, same day service completion
  • Complimentary local Lyft for your convenience
  • Original Equipment equivalent or better quality parts
