Ford x-Flow Highly Modified manifolds - still look OEM

Ford 6 alloy head crossflow manifolds that are available on a change over basis,These will out flow you average x-flow manifold as we have done the testing. They have a port variation of around 3 CFM on all 6 cylinders. OEM STD approx 10 CFM diference. These highly Modified intake manifolds flow around 25% better than the stock manifolds. They are suited for classes where a visibly standard Ford manifold is required. They are not cheap as there has been many hours gone into the R&D time & jiging to produce them.

Conditions - I will need your old std manifold posted to me, the extream make over gets done, then i will post it back to you 

THIS IE A EXCHANGE BASIS
