The STOL nose bowl is an evolution of my 2003 design I had in production until 2019. It provides even more inlet air and has built in inlet rings based on 5.5” inlets. It was initially flight tested in Yuma Arizona to measure its' comparative cooling potential. The subject aircraft saw a 70F reduction in engine temps on the climb out. The was no measurable reduction in top speed. This nose bowl is directly retrofittable to any previous installation, uses the same cowl sheet metal, same interior baffles and the same spinner and location. Made in USA
