Our basic cooling system assembly and scoop are priced at $1,350 . Our complete kit; which is our cooling system assembly, scoop, oil thermostat, all fittings required, all hoses requires, all clamps required, oil can bracket, oil catch can, coolant reservoir, heat soak vents, and hardware, is priced at $1,950 . Propeller, spinner, throttle system, and more miscellaneous items are available to complete your installation. These assemblies (and additional optional components) are compatible with Sonex, Waiex, and Xenos, both A and B models. It requires the use of Sonex Aircraft's engine mount and attach bars, cowling side vents (And yes, the A model uses them too), Toucan exhaust system specially designed for Sonex, and Sonex's Rotax propeller spacer. We HIGHLY recommend a horizontal split cowling and do not support the use of a vertical split cowling. From there the components are mount, plug, play.
