Honeycomb seat ferring?
 

I was wondering how much the plastic honeycomb seat insert was to replace. And also what it was called. Is it a ferring? I don't know what it's called. The driver side the top clip snapped off so it doesn't stay on very well at all. I already had to go back on the highway once to go and get it. Any thoughts?
Thanks.

It's called a Wind Deflector and the PN# for the Driver Side is 986.561.583.01C

You can often find them on ebay, usually in pairs. They're spendy from the Dealer or other suppliers - much more than you'd think just to look at it.

Rather than replacing it, you could try using some double-sided foam tape to secure it, or even some wire ties.
