A magnetic oil drain plug helps catch fine metal particles floating around in your engine oil. Every engine creates tiny wear particles over time, especially as components bed in, age, or get pushed harder. The magnet gives those particles somewhere to collect instead of letting them keep circulating through your oiling system.

Choose the EJ/EZ version if your Subaru has an EJ 4-cylinder or EZ 6-cylinder engine. This commonly includes many WRX, STI, Forester and Liberty models.

Choose the FA/FB version if your Subaru has an FA or FB 4-cylinder engine. This commonly includes many newer WRX, BRZ, Forester, Liberty, Levorg, Outback, XV and Crosstrek models.

Some fine metallic paste can be normal over time. That’s the plug doing its job.

However, if you’re seeing larger shavings, flakes, chunks, or a sudden increase in metal from one service to the next, that can be a warning sign. In that case, don’t ignore it - inspect further or speak to a Subaru specialist.
