If you have the below fairings, and you are not happy with your CHTs, there is possible help by removing those two fairing pieces. CHTs may drop 15F across the board, which can be just enough to obviate peaks in the climb. The method seems simple enough, it increases the lower cowl vent opening, and likely channels the under cowl air flow for better draw.
This is from my Dakota, but many PA32s, and some other PA28s have the same fairing. I discovered this entirely by serendipity -- but the owner of a large shop at my field, when I mentioned my discovery, said, "Oh yes, that is a winter fairing, should be removed in summer." I had never read that, or heard about that from anyone else.
To buttress the now two loose ends my mechanic made up a piece of aluminum, with a bend to give it strength, anchored with the same screws and lock washers the original fairing was held in place with. That same structural bend also creates an inverse wing, like a mini cowl flap, to perhaps enhance the draw and cooling. AFter the pic was taken, the free leading edge of this strip was snipped and bent upward, with the same effect in mind.
Note, that you may have to twist an arm for the paperwork, to make this happen.
