I went to my buddy's house to change brake pads, so i did and when i backed up the car this blue rubber gromet with the wording oil proof rubber was on the floor, i had never seen it before, and neither had he, so we dont know if it actually belongs to my car, recently i had done a clutch swap, aem cai and barke pads but i dont recall ever seeing this part.

 

Some sort of of bushing for the clutch?

 

maybe part of one of the axle boots?

 

It's not an OE part - that's for sure.

Maybe some grommet for the mounting of the CAI?
Other than that, I can't imagine what it is.

 

if its not an oe part then its not from my car, because I did all the work myself and dont recall ever seeing that part.

thank's
