LX9 3500 = our 3400s but redesigned.

Stock vs stock the intake manifolds and the cylinder heads are a more superior design than our intake manifolds and cylinder heads. Switching to them increases how much air is capable of flowing into your engine.. You dont really want to swap the 3500 upper intake manifold onto our cars because its more of a hassle then it is worth. I dont think the 3500 upper intake manifold increases horsepower just broadens the powerband.
