Ford Focus ST Mountune air filter installation and side by side comparison with Cobb air filter

[@Frenko1]

Turbo sounds amazing! I might have to put exhaust, I'm just worried it'll way too loud for my tasting.

Thanks bro, yes it’s too loud most of the time 😆

If you just put a mountune filter on a Focus ST 2016, with no other mods and completely stock, will it still sound like this?

[@RS-ft7nv]

Yes it will sound different as long as you don’t put the top cover on. I’m not sure if it will sound exactly the same but you will hear the intake alot more.
