Linea_rossa_2_2 Hi guys Ive come across a cast iron saab inlet manifold for the z22se and was just wondering if there are any advantages to using this over the standard plastic one? Are flow rates/air flow the same or better etc? Thanks
evocarlos there alloy think the only real difference is the weight what with this one being heavier than the plastic manifold would be a good addition to a turbo mod or for the use of NOS for N/A not sure there any gain
