I am working on the bottom cowl assembly with the large air filter on my wide body Backcountry Cub. The two vent flanges which came with the kit are too long to fit between the air filter fairing and the edge of the cowl. The Piper PA-18 drawing #12357 shows these parts. I have found photos on this site showing different combinations of vents flanges. Some have these two on either side. Some do not. Some have the aft cooling lip at the main air outlet and some do not. Some do not have any vent lips. What combinations are some of you using and what cyl head temps are you getting with a 180hp engine when you operate on hot 80+ degree days. Also what is the distance between the side cowl and the boot cowl at the maximum point.
Cooling is important. I want to get it right the first time. Thanks for your inputs.
