It's a small filter (imagine a mini induction kit) Which vent's petrol fume's to the atmosphere instead of back in to the engine. So in theory the car is sucking in cleaner air. The downside is that your engine bay will stink! The fume's can also come in to the cabin through the vent's, depending on where you mount it. It's also not very good for the environment!

Its none of the above... it stops oil been drawn back in through the inlet from the rocker cover, instead it just drops back onto the cams

basically you drill holes in the plate under the rocker cover

Mines been drilled out, though I have never taken mine any higher than second gear... It's MattB's rocler cover off of his LET though, which used to belong to the guy who runs that website... In fact, I think that might be my rocker cover
