I am after a twin throttle system with a suitable Mace air flow box,do you still make this twin throttle body manifold?

Unfortunately we no longer manufacture or stock the twin throttle body manifold, due to lack of demand..Also, we have found that by fitting our intake manifold insulators and spacers as well as our 69mm throttle body you get approximately 90% of the gains of the twin TB manifold but for about 20% of the cost when you take into consideration that the twin TB manifold needs to be custom tuned..In regards to the cold air intake kit, assuming you do end up running a twin throttle manifold, then I would recommend one of our universal cold air intake kits to suit assuming your ecotec is in a VL-VS body shell
