I have a Mazda 3 and the Plastic that covers the front under carriage under the engine has cracked off. It is the piece behind the front bumper under the engine. Does anyone know if it should be replaced and what the cost would be?
Thanks

 

177 installed. for a god damn plastic piece.

 

unless u live in an area with a lot of pot holes or rocks i wouldnt even worry about it, but you have to be a moron if u cant figure out how to replace that overpriced plastic sheet. As for the price of it try ebay would most likely be the cheapest way to go, if not go dealer. good luck
