whats the part that goes on the inside of the wheel housing. It looks like a tarp and i think its used to keep dirt/snow from getting to the engine/horns. Mine recently fell off and needed to replace it but no idea wut the part is called.

 

Fender liner?

 

You can look up the names and part numbers for stock parts for Acura parts on the Delray Acura website and for Honda parts on the San Leandro Honda Parts website. You can also order parts from both websites.
