Spark Plugs Replacement in Walnut Creek, CA

Spark plugs replacement is one of these maintenance items that will recur throughout the life of your vehicle. Our Walnut Creek auto care facility offers hundreds of auto services and repairs, including diagnostics and spark plugs replacement. Typically, spark plugs need to be replaced at 30,000 mile to 90,000 mile intervals. Such huge range is simply due to the materials used in the manufacturing process. Copper spark plugs will typically last around 30,000 miles, while Iridium spark plugs can often go for 90,000 miles. Naturally, at Diablo Auto Specialists we will select spark plugs that best match your vehicle’s requirements.

When the spark plugs start failing, the check engine light will come on. If the problem is severe, you may notice engine misfire. Decreased engine performance is another symptom that can indicate failing spark plugs. If you notice any of the above symptoms, bring your vehicle to our Walnut Creek auto repair shop, and our technicians, certified by the National Institute for Automotive Service Excellence (ASE), will perform an inspection of the electrical/charging/starting system, and will provide you with answers as to the root cause of the problem. If the spark plugs need to be replaced, we will let you know and let you know replacement options, and once you authorize the repair, we will get it accomplished, usually the same day.

The reason why we recommend professional inspection at our Walnut Creek auto care facility is that the symptoms of failing spark plugs are similar to those caused by other subsystems. So without a professional inspection, it would be only a guess that the spark plugs should be replaced. Spending hundreds of your dollars on a guess is not something we would do at Diablo Auto Services.
