Wow. I thought i might have wasted my money here because driving my daily commute at up to 40mph there was absolutely no difference in engine tone, performance or economy at all. However, after taking a trip down some 'A' roads today (that started as a 5 min test and ended up at an hour) there is a clear and definite change in the car once it gets past about 4500 rpm. The engine is definitely freer revving up to the red line and it sounds deeper, sportier and less laboured. It might not make much difference to overall performance, but for £35 this gets 5 stars. Get one!
