im wanting to buy a cosworth plenum. but dont know if id be wasting my money and better off just doing the motordyne plenum spacer either the 5/16 or 1/2 spacer and possibly the mrev 2 manifold the car is a 2006 modle but i cant decide.
also when i check the motrdyne website they offer the plenum spacer,mrev2 manifold,and a manifold spacer. is it me been a knob but isnt each one just the same??????????????????????
please any help or advice on best mod to do would be great.
