Splash Guard
 

The splash guard i believe its called underneath the engine is partially hanging down and must be held up with zip ties now. I went to the mazda dealership and they told me i must replace the whole thing totaling over $500 for parts. My question is, is it completely necessary to replace this and get a new one? Or could i just tie it up so that it can still remain under the car?
Also the other problem would be that every time i get an oil change i must take the back portion of the splash guard off so i can reach the oil filter due to the splash guard being put up a little off. Other than that i would assume its still fine to do its job as protection?
(By the way the reason the splash guard is hanging a little is because i hit a tire in the middle of the road and part of the splash guard broke, other than that theres no damages to it other than scrapes)

Corksport makes an aluminum skid plate for Mazda3/Speed3 for $249

or if your car is newer than the above

I cut a larger hole & cover to access my oil filter so I don't need to remove the cover. So you can do the same thing & tie wrap it otherwise.
