A Japanese-spec E15ET inlet manifold is an easy bold-on modification for Australian-delivery E15ET’s. This manifold features longer runners and theoretically has marginally better flow properties over Australian E15ET manifolds.
Noteworthy is the fact that the design of these manifolds is such that the installation of one on an E15ET will realign the orientation of the throttle body and pre-throttle ducting. The Japanese manifold will align the inlet tract to enter the throttle and manifold from the passenger’s side of the vehicle and parallel, rather than perpendicular, to the cylinder alignment.
Prices will vary according to demand and supply for this part. Expect around the $100-200 mark.
