The best oil filter for a Subaru WRX STI is the genuine article—the Subaru 15208AA15A Oil Filter, which is the OEM part sold directly from Subaru.
Oil filters are crucial for your engine’s overall health. The oil filter removes dirt and contaminants from your motor oil while it flows through the engine, allowing the oil to stay clean longer and keep your engine running at peak efficiency.
Oil filters must be changed regularly—usually every 7,500 in modern filters.
While the Subaru OEM is a great choice, there are plenty of other good options. A few other oil filters to consider for your Subaru include:
  • Purolator PL14610 PurolatorONE Advanced Engine Protection
  • Mobil 1 M1-110A Extended Performance Oil Filter
  • FRAM Extra Guard PH6607
