BMW Spark Plugs

Spark plugs are the parts in your BMW's ignition system that cause a spark in order to get the combustion process going that you need to start your motor. This then powers up the vehicle so that you can drive it. Spark plugs don't typically need to be changed often, but this can vary depending on how often you drive your vehicle and the type of driving you do. Like anything else, they can wear out over time and you should make sure you get a new set right away. There are some things you can watch out for that might suggest you need to get some replacement spark plugs. You might notice frequent misfires of your engine when trying to get it started. You also might start to notice a drop in fuel economy. This is caused by the combustion process not going as smoothly, leaving your engine to compensate and burn more fuel. When you need a new set of spark plugs, you should make sure you're investing in OEM parts. Only OEM spark plugs are going to fit your BMW the way they should. Aftermarket spark plugs can corrode more easily and wear out sooner. Shop our site for genuine BMW spark plugs.
