Make sure that your Sierra starts up smoothly every time with upgraded and replacement ignition system parts. The ignition system is responsible for starting up your engine and igniting the fuel in the different cylinders of your engine. When the ignition system is performing properly your engine runs smoothly and evenly, but when it's not doing so well you can have a misfiring engine or an engine that just isn't running at all. One of the first replacements that you should make to your ignition system is the Sierra spark plugs. Invest in quality plugs that are built to perform for tens of thousands of miles. Get a premium set of plugs that will keep your engine running smoothly and that will generate sparks for a very long time. You can also upgrade the spark plug wires as the old ones wear out, though that isn't necessary until long after you swap the original spark plugs out. Along with the spark plugs and wires, you should keep an eye on your truck batteries. Your battery is responsible for starting up your pickup when it's not running at all. The battery will get your engine turning and start up the initial ignition phase so that the engine can get running properly and quickly. A worn out battery won't have the power to start your truck, and will be less reliable in cold weather conditions as well. Fortunately, decent batteries are affordable to purchase, and getting a rugged battery for your pickup will pay off with good smooth starts all throughout the winter season. We also carry part replacements for less common components such as the Sierra ignition coils. The coils take power from the battery and translate that into massive power surges strong enough to get your engine spinning and running properly. Without good ignition coils you won't be starting your Sierra anytime soon. Whether your engine isn't running properly or it isn't starting, we have the parts you need to resolve the problem at American Trucks. Invest in them and your truck will instantly become more reliable.
