This is new old stock – never used but might show a little shelf wear.
It's a Piper oil cooler winterization plate, part number 66561-000, also known to cross with 96771-00.
Fits Piper Seneca and several other models.
Basically, it blocks off part of the oil cooler airflow to help your engine reach and maintain operating temperature in cold weather.

No warranty, but that's typical for NOS aviation parts – they're genuine and built to Piper's original specs.
Easy to install with basic hand tools, just bolt it over the cooler inlet.

Great for owners or mechanics prepping for colder months.
Made from durable materials, designed specifically for Piper aircraft.

Solid addition to your winterization kit.
