Unless you drive an electric vehicle, spark plug replacement will be a regular part of your vehicle’s maintenance. At Berkeley Bob’s we offer spark plug replacement as part of our comprehensive automotive maintenance services. Internal combustion engines require spark plugs to generate the spark that ignites the fuel-air mixture which create combustion and power the engine. Spark plugs can last as little as 30,000 miles or as long as 90,000 miles.

Spark Plugs Replacement in Berkeley, CA - Berkeley Bob's

What Are the Signs of Failing Spark Plugs?

The most frequent symptom will be engine misfire, which in turn will results in onboard computer turning on the check engine light. Other symptoms to watch out for are decreased engine performance, difficulty starting or rattling noises.

If your vehicle exhibits any of the above listed symptoms, bring it to our Berkeley auto care facility, and our nationally ASE certified technicians will perform a comprehensive inspection and testing to determine what the cause of the issue is.  This will include checking the starting/charging system along with engine performance. If we find the spark plugs are old, worn or causing the problems your vehicle manifests, we can have them replaced the same day. You can also expect:

  • 36 months / 36,000 miles warranty on parts and labor
  • ASE certified technicians working on your vehicle
  • Early bird drop off and after hours pick up available
  • Discount rental cars available
  • Free digital vehicle inspection with service or repair

Replacement of your vehicle’s spark plugs should be part of the normal vehicle maintenance which is advised by the vehicle manufacturer at certain mileage intervals.   The frequency depends in part on the material the spark plugs are made.  However, a failed spark plug is usually caused by unaddressed engine problems like a check engine light that is on, poor fuel quality, lack of overall maintenance and high mileage. Today most spark plugs are made from platinum or iridium and the car manufacturers indicate these will last between 30,000 and 90,000 miles depending on the model.  But don’t wait until spark plugs fail to replace them as delaying their replacement or driving with a failed spark plug can cause serious damage to the engine or catalytic converter.  They need to be part of a regular service plan.

When you bring your vehicle to Berkeley Bob’s you can expect friendly service advisors, as well as technical excellence on the part of the mechanics who perform the work on your car. In addition to being the premier Volvo service and repair shop in the entire San Francisco Bay area, we also work on Japanese and Korean vehicles including hybrid cars.
