yea the 1.6 & 1.9 aaz intakes bias the center two cylinders. the PD intakes, while still not as good as a dual plenum manifolds are still wayyy better than the 1.6 or 1.9 aaz intakes.
I do know that I drive torque, while listening to my friends prattle on about horsepower.
Does anyone that you know of do custom intakes?I'm grasping at straws here.
What about the 1Y intake?
