Smoother Starts. Stronger Acceleration.

Spark plugs are small but critical. They ignite the air-fuel mixture inside each engine cylinder thousands of times per minute, powering your vehicle forward. Over time, spark plugs wear, foul, and lose their ability to fire consistently, leading to misfires, poor fuel economy, and reduced power.

At Krietz Service Center in Frederick, MD, our ASE-certified technicians replace spark plugs with manufacturer-specified parts for all makes and models, restoring smooth engine operation.

What The Service Includes

Spark plug replacement at Krietz Auto is a thorough service that ensures your ignition system is firing correctly:

• Spark Plug Removal & Inspection: Careful removal of existing spark plugs and inspection of their condition to identify signs of engine problems such as oil fouling, carbon buildup, or lean/rich running.
• New Spark Plug Installation: Installation of new spark plugs matched to your vehicle’s specifications – copper, platinum, or iridium – torqued to the correct specification.
• Ignition Coil Inspection: Testing ignition coils and spark plug wires (where applicable) to ensure they are delivering proper voltage to the new plugs.
• Gap Verification: Confirming the electrode gap on each new plug matches manufacturer specifications for optimal performance.
• Anti-Seize Application: Applying anti-seize compound to plug threads where recommended to prevent future removal difficulties.
• Complimentary 30-Point Inspection: Our comprehensive safety inspection covers all critical systems beyond just the ignition.

When Spark Plug Replacement is Needed

Replacement intervals vary – copper plugs may last 30,000 miles while iridium plugs can go 100,000 miles. Regardless of mileage, replace spark plugs if you notice:

• Engine Misfires: A noticeable stumble, jerk, or momentary loss of power while driving, caused by incomplete combustion in one or more cylinders.
• Rough Idle: The engine vibrates, surges, or sounds uneven when idling at a stoplight or in park.
• Poor Fuel Economy: Decreased miles per gallon as worn plugs fail to ignite the fuel-air mixture efficiently.
• Slow Acceleration: The vehicle responds sluggishly when you press the accelerator.
• Hard Starting: Difficulty starting the engine, especially in cold conditions, because worn plugs cannot generate a strong enough spark.
• Check Engine Light: An illuminated check engine light, often accompanied by a misfire diagnostic code.
