The m3 vents are right above the manifold and open intake if you have one, thus exiting a good amount of that hot air noone wants, and honestly, theyre small nuff, wont make a huge difference as far as engine dirtyness unless u leave em open thru every rainstorm, etc. Which is why they have the open and close function
