I just bought a 2013 Fit for my daughter. I found this part in the back.

What is it? It is marked TK6 L 889 but searching for that part number does not give me any clues. It is flexible and made of black rubber.

Thanks!

 

That is called a "strake", there were a pair, they were supposed to come with pushpins and it was to be installed in the front of the rear wheel in the bottom corner of the fender.

It's basically a little air deflector that hangs down below the body line in front of the rear tires.

If you only found one inside the car, check if the other is still attached to the car so you can see how it's installed and held on

 

Awesome - Thanks. I'll poke around and see. I have some push pins so it should be pretty easy to put on, I think.

Thanks!
