hello mate, in answer to your question, yes get yourself an ecotek cos i did and it saved me about £10 a week and tuned right (you do need to tune it every now and then) it made the car a bit faster or at least feel a lot smoother.
its gonna take ya about 10mins, all you do is cut the breather pipe as near to the inlet as possiable, pop the valve in, using 2 hose clips secure it, and thats it. really it only takes a few mins so do it yourself. oh yeah get the Silencer / muffler or you'll get a weird noise that is well annoying. good luck
