Subaru WRX STI Spark Plug

Your WRX STI is a prized possession.

The vehicle in your driveway symbolizes the best in class when it comes to all the cars, trucks, and SUVs on the road today. Obviously, you bought your WRX STI because you understood you would be getting reliability and great value both impeccably combined into one vehicle. While it's not hard to buy replacement parts for Subaru vehicles, these days the necessity for nothing but the highest quality are required to maintain your automobile. When your Subaru WRX STI left the factory, it was destined for a driver who values a fun driving experience in their automobile.

Why Spark Plug replacement is so important.

Some engine parts are tucked away out of sight, so they can be forgotten about when performing regular maintenance. The job of detonating the air/fuel mixture in the combustion chambers in the engine is your Subaru WRX STI spark plug. Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. If one of the spark plugs wears out, the engine in your Subaru WRX STI will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.
