The ignition system in your Acura is a complex selection of parts that all work together to help with the combustion process. The spark plugs are one of these parts that work to receive high voltage currents from the ignition coils. This current is then used to generate a spark that ignites the air/fuel mixture in your vehicle's combustion chamber. This happens over a thousand times per minute when you are driving and is what is responsible for the continuous movement of your car over the road. Your Acura's spark plugs should look clean and have no damage to the electrodes so that your engine can run at peak performance. Dirty or fouled spark plugs can have a big impact on how your engine runs - and can cause a whole host of problems down the line as well. Some warning signs that you can look out for when it comes to the condition of your spark plugs include engine misfiring. This can show itself in a variety of ways - from your engine having stumbling problems before regaining power to an increase in exhaust coming from the vehicle. Increased fuel consumption is also a big indicator of spark plug failure. Be sure to buy OEM spark plugs when replacements are needed from our web store here at Curry Acura Parts!
