These aluminum cooling louvers are custom made and designed to improve the cooling of your engine compartment on your experimental aircraft. They are simple to install, and will dramatically lower your CHT temps, as well as your oil temperature.
The standard size of the aluminum plate is 12” long and 5” wide, and the outside flange can be trimmed to fit your application. There are a total of 9 louver slots which aid in cooling.

ALUMINUM COOLING LOUVERS 12X5X.032
Nice and simple, worked great for fender vents on the race car
This product is very high quality and works well. Brought my CHT temperatures down and they look really nice too!
These are well made and worked perfectly for my application
Delivered as promised and looked great, can’t wait to install on my 1961 Shasta Trailer.
Very high quality item. These are made from a soft grade aluminum to avoid cracking. Not sure what previous poster is talking about, but I have used about 10 of these over the past 5 years and they have always been excellent quality and easy to install.
Ive used a bunch of these louvers. They work great and are very high quality.
These are cheaply made. Every louver has cracks from stamping. I probably will not use. I am going to make some from scratch.
