My '98 TJ Sahara had at least two previous owners.
Now with 160,000 miles, it's been reliable (knock on wood)
but I decided to check the air filter.
To my surprise, a shiny silver turbine-like cylinder was resting on top of the filter.
It was engraved KI 55 Tornado. https://www.tornadoair.com/
I'm no automotive engineer, maybe it might do something for a carburetor intake,
but I just don't see how it could help in front of a three foot long air intake
for a fuel injected engine. I did not put it back in.
