Read on some of the threads that a few people have removed their intake resonator which is in the wing. Will this increase induction noise and air flow? My car is a 2010 sti hatchback, was thinking about doing this mod along with a cosworth filter. Worth doing?

 

In some cases im told it can lose u bhp / but will make a bit of a roar !!!

 

I deleted my resonator on my bugeye and yes its louder but not by much, and I really havent noticed a power difference. Your car is pretty new, if I was you i'd just leave it stock or do a proper upgrade and tune it.
