Message	The upper and lower intake manifolds (plenums) are the same TT and NA 90-92. Newer ones are different from the earlier ones. They made the change to the new style injectors, lower plenum, and the intake port on the heads in 93 for the NA but not till 95 on the TT. So the lower plenum and heads on a 93 -94 NA are different than those on a 93-94 TT. The upper plenums changed just a small bit in 94 when the angle that the flange of one of the EGR tubes bolts on to the plenum rotated about 30 degree angle.
