Subaru Spark Plugs

When you start your Subaru, nothing happens without ignition. That's provided by the spark plugs in your vehicle, which create the flash that ignites the air and fuel mixture in the engine. To create that flash, they shoot an arc of electricity through the gap between two leads. Gaps are precisely calibrated to produce the proper sparking. Once you've achieved ignition, the engine starts cranking, pistons start pumping, and you're ready to head out on the highway. Diesel engines are more likely to use glow plugs, which feature a heating element in the tip that ignites a mist of fuel in the cylinder. Whichever type of engine your Subaru employs, you can be sure that it came with the factory-installed plugs that do the best job.

Trust Genuine Subaru Spark Plugs

Over time, even the best spark plugs can start to falter. Whether due to corrosion or widening gaps, the spark becomes weaker. This leads to cranking the starter for a longer period of time. Eventually, engine misfires show up. Rather than assume that a faulty alternator is the culprit, consider that your original Subaru spark plugs have a lifespan of around 60,000 miles. To be sure of your recommended maintenance schedule, check the owner's manual. It's not advisable to try to go too far past the rated mileage shown there, as you may be putting your BOXER® engine at risk for damage. The best spark plugs for your Subaru?
