Engine Air Filter, OEM - G01 X3 30i & G02 X4 30i

Since the quality of the intake air has a direct affect on performance and efficiency it just makes sense to have a clean air filter. Clogged and dirty filters will prevent good airflow to the engine and the engine computer has no choice but to compensate. To help keep your engine running at its optimum best, always replace or clean your air filter once a year.
