current-production versions.
The E-Tech™ engine has undergone a left-side redesign. Changes include a new plate-type oil cooler and a new oil filter mounting arrangement.
This new oil filter arrangement includes a new centrifugal oil filter assembly, where the centrifugal filter assembly is now mounted upside down, and the external oil drain is eliminated.

This new centrifugal oil filter is called Centri-Max PLUS. The engine electronic control unit (EECU) has been relocated to the left side of the engine and is mounted on a new one-piece inlet manifold. Relocating the EECU has eliminated the need for the EECU cooling plate, and has also brought about a design change to the unit pump front outboard heat shield. Additionally, with the change to the one-piece inlet manifold, the fuel filter mounting adapter is new and is located slightly forward of the previous location.
