These are comparison pictures of the KLDE and KLG4 Intake manifold along with rough measurements.
Below is a comparison of the inlet of the manifolds, as you can see the KLDE manifold features VRIS butterfly’s directly behind the throttle body as a large obstruction.
While the KLG4 Manifold is a direct to plenum inlet, although smaller inlet diameter then the KLDE.
In the next comparison shows the rear section of the manifold. the KLG4 has larger plenum volume that are more free flowing. It also features the VRIS as one large butterfly connecting each plenum.
Below are various picture comparison’s with measurments.
