I recently bought a new leftover 2016 Focus ST and im already looking at getting a cold air intake for mainly the sound.

What are your recommendations on one that sounds good and has decent proven power gains? So far, I know of Injen, Roush, and K&N

I will be sticking with a stock exhaust for now.

Thanks,
Mike

Thanks for your opinions guys. Based upon my budget and what I am sensing... it is best to just replace the airfilter with either a Green Filter or a K&N and leave the airbox alone for now. (Might get CAI when i get an MBRP exhaust) but for now it appears the noise from a CAI compared to a re-usable filter with stock airbox, doesnt make much of a difference in both power and noise.

doesn't leaving the lid of the airbox off create more heat in the engine bay? Not something i really wanted to do. AEM dry filter does seem like a good buy, but if it doesnt offer any sound difference the only purpose of it is for re-usability

Is that the RS airbox cover? For $50 i will buy one! I ended up getting a Green Filter and that would go nicely with it, i imagine it will sound a tad bit louder as well.
