Just took my car to Mick, at Pitlane Auto, standard 2005 mdl Typhoon man, bocsh 968 42lb injectors, k and n filter, plugs, thermo-stat + tune and got power of 294 rwkw. Car is running sweet, but standard bov diaphragm has slit in it. Have blanked it off but wondering if any one has a standard bov for sale?
