Nice fiberglass
I can say the quality of the fiberglass work is good. Started installing mine yesterday, but can't say as to if it will help lower the temps as I am not flying yet.
Install looks like it is going to be easy.

The whole point of a plenum is to eliminate flap seal leakage. If you have truly closed all the flap seal leaks, adding a plenum will do nothing.

How does the oil door interface with the plenum? Do you have to build the hole, or does it come with baffling?
John
I have a Sam James plenum on my 195 HP 7 and it works great. I have even CHT's and overheating is never an issue. They are all within 25 degrees of each other. The issue I had was high oil temps in the summer. I solved that with a larger oil cooler and increased the Scat tube to 4 inch. Before that it was a real problem no matter how well i nursed it to altitude.
Here's what others have done John. Not sure about the RvBits specifically.

I agree with DanH though, if the baffles are properly done, a plenum does nothing for you--other than add labor time during spark plug & injector maintenance.

No need to worry about an oil door in the plenum for 4 cylinder Lycomings. Only 6 cylinder ones. On the 4, the oil filler is aft of cylinder 3 (and the plenum).
