I riveted the additional bracket onto the oil cooler and reattached it to the engine mount.
There will be one more adel clamp and bolt when the oil cooler is installed for good. This is just installed temporarily so that I can fabricate the plenum.
I cut down the foam block a bit more and then determined where the butterfly valve would need to be positioned.
Afterward, I did some further shaping of the foam to define the final shape of the plenum.
Here’s a better shot. The bevel cut on the left edge allows the plenum to clear the engine mount tube. I’ll probably tuck a small foam wedge there so that the plenum extends under the engine mount tube to allow air to flow through the entire oil cooler.
