just get a cheap one off ebay. threads on here that will help with where to mount it. there are diff variables in what way to do it, each to there own reli.
theres not reli any point in spendin loads of cash on a "can" they all do the same thing, keep ure pennies for something thats really helpfull. makes sense
i have a cusco one but ive left it off. just usin a breather, when i had it on before i had a hose comin from the crankcase breather,( just below where the oil goes in) to the can, then a hose comin from the can to the atomosphere,( venting it towards the rear off the car for a better vacuum)
