Service Time: (Approximately: 5-15 +/- Minutes)


  1. Increase Gas Mileage: Helps to improve fuel mileage.
  2. Increased Power: Worn and fouled spark plugs create reduced engine power.
  3. Smoother Idle: New spark plugs create better spark resulting in smoother idle.
  4. Engine Performance: Aids in engine performance as mentioned at top.


  • The spark plug emits electricity across a small gap, which creates the ignition for the combustion needed to start your car.
  • By putting the engine’s pistons in motion, your car can stay powered & produce a smooth burn of the air-fuel mixture.
  • When a spark plug ignites, it has to travel across a gap of space in order to provide the right level of combustion (spark) at the right moment in the crank cycle.
  • As spark plugs age, this gap widens as a result of extreme temperatures, debris, and normal wear and tear.
  • If the gap is to far apart, engine horsepower decreases, gas mileage becomes worse, and engine life may be affected.
  • From the first time your engine is started, dirt, carbon deposits, and varnishes are formed in the combustion chamber and spark plugs.
  • Here are some symptoms that are caused by faulty spark plugs and wires:
    • Poor fuel mileage.
    • Rough idle and acceleration.
    • Lack of or poor performance.
    • Compression leakage.
    • Carbon tracking from the wire to the spark plug.


  1. Mileage and/or Time: Services are due based on manufacturers recommendation of mileage and/or time.
  2. Testing and/or Condition: Excessive wearing in the gap of plugs are signs service has not been performed recently.
  3. Abnormalities: If engine barely runs, has a dead cyl., etc. (see repair facility for further diagnosis & repair)

*Disclaimer: All Additional Services are Recommended Based on Mileage, unless otherwise noted or previous service history is available to reference.
