The Aero‑Classics 8000216 Oil Cooler is a remote‑mount oil cooler designed for piston aircraft engines, with a 17‑row drawn cup core that provides enhanced heat dissipation compared to smaller coolers. It is FAA‑PMA approved, meaning it is a certified replacement for OEM coolers and includes FAA 8130‑3 paperwork. This model features corrosion‑resistant construction, optimized internal oil flow, and 3/8″ NPT inlet/outlet fittings for integration into engine oil systems. It is typically used with Lycoming engines and similar installations, mounted on the airframe or baffles with hoses connecting back to the engine.
