How long to spark plugs last?

Are you feeling an infrequent stutter when you hit the gas; almost as if you are losing power for no reason? Does this also happen when you try to start the car as well? From this list of symptoms, most would assume either a fuel or ignition problem. Typically, fuel problems are accompanied by the familiar smell of gas. An ignition problem, obviously, doesn't smell like gas. It will likely interfere with other electronic systems in the car as the levels of current jump around. You might see driving or interior lights flicker or dim along with these engine power losses. After that you can pretty much bet on a failure in the ignition wires or spark plugs. Every engine requires regular maintenance, and at set intervals your spark plugs and wires should be inspected and replaced if necessary. Waiting until you experience a failure like this only jeopardizes your safety and keeps you off the road. Changing the spark plugs every 90,000 to 120,000 miles is a responsible way to ensure the engine is getting a powerful enough spark for reliable detonation and ignition.

Where did spark plugs come from?

New Spark PlugsThe very first time a spark plug was used in an internal combustion engine was by Belgian inventor, Etienne Lenoir in 1860. Automotive applications soon made their debuts towards the end of the 19th century, as inventors such as Tesla and Bosch saw the potential and application for such a useful device. Your spark plug delivers tens of thousands of volts with each spark, and it does this by ionizing gases between two electrodes inside the plug. Once the voltage accumulated from the ignition coil is too high for the gas, it creates a small explosion (like lightning) of heat and electrons across a small gap. The spark plug sits at the top of your combustion chamber, and at precise intervals releases these sparks to detonate the compressed air/fuel mixture causing your pistons to turn.

A fun, easy job.

Changing your spark plugs is super easy. In fact, on some cars it's harder to access the plugs than it is to change them. In those cases where it involves the removal of numerous components just to see the coils and plugs, we recommend professional installation. But if you can pop your hood and see the spark plug wires right there on top of (or next to) your valve cover, then the process should only take a few minutes. The first thing you need to do is make a note of the position of each ignition wire. Once you change your spark plugs, you'll have to connect the wires exactly where they were before. Next, pull each wire off the plug. If you have direct ignition (coil on plug), then you'll have to disconnect the wires from the coils, and then remove the coils. This will expose the spark plug terminal. Using a special socket, unscrew the spark plug. At this time, you can also inspect and replace the spark plug seals as well. Now simply install your new plugs, reconnect the coils and/or spark plug wires, and you're done.

Little parts, big difference.

Regular vehicle maintenance is the key to keeping your car or truck running for the longest time possible. The more miles you put on your vehicle, the more you will have to put into its upkeep. Getting new spark plugs is one of those things you have to do every couple of years in order for your engine to function properly. At Car Parts Discount, we offer the top names in spark plugs for all engines. So that means fewer trips down to the local auto parts store where you'll pay more money for the same thing.
