Fiat X19 LP HP Intake Manifold
#32150 from Daniel Snow · Taken care of · Minutes (2022-03 Fastrack)
Thank you for your letter. The consideration of manifold porting or the use of an alternate non-USDM stock intake manifold for
the limited-prep Fiat X1/9's in HP was already considered and responded to via Letter #31602 in the January Fastrack. These
cars also received a weight reduction via Letter #31653 in the January Fastrack, and the results of that need to be seen.
