Subaru WRX Upper cylinder clean
Does my Subaru WRX need an upper cylinder clean?
A Subaru WRX upper cylinder/engine clean removes carbon deposits and other contaminants from the air intake and combustion chamber, without having to pull the engine apart to do so. An upper cylinder clean can improve a Subaru WRX’s performance, so it runs at it’s best.
Carbon build-up, grime and contaminants are part of a Subaru WRX engine. If left to keep building up it can eventually lead to drivability issues and the engine will run rough and become less reliable. Over time this can lead to engine damage, if the Subaru WRX continues to misfire.
There are various ways to clean a Subaru WRX’s upper cylinders by spraying upper cylinder cleaning into the throttle body, attaching a line to a vacuum hose to the intake manifold and/or spraying into each cylinder via the spark plug holes.
A professional automotive mechanic can carry out a Subaru WRX upper cylinder clean. They have the tools, knowledge and experience to know what cleaner is best for your Subaru WRX and the best method to get the best results.
