2007 WRX air filter upgrade - recommendations ?

[Lux_Great]

Hi

 

So the GB270 is soon heading to my driveway.  Saying good bye to my excellent Legacy Spec B after 7-years ownership.  On the Spec B I fitted a Pipercross air filter.  It made a difference.  Any air filter recommendations from 2006-7 WRX owners ?

 

Cheers

I use 'green' air filters, they are decent price and performance.

They always get good reviews too
