Third time buying this and find that this filter and also Blitz filter provides best performance
- Installation tips
This one is thinner than the OEM filter so it is easiler to slide in the slot of the air box.

The Zero sport air filter fit my forester original air intake box perfectly. The air charger sound is subtle, not much difference to the genuine one, but the low rev torque is noticeably improved.
