I just realized today that my 2012 Prius C at one time had dual splash guards under it to keep water and debris away from the engine area and to aid in aerodynamics. Many people throw them away so they can save a few minutes when they change the oil and filter, etc. Should I bother with buying a pair of them and installing them? They would cost about $70 and are not original OEM. They seem to have about 20 screws holding them in place. I live in upper East Tennessee. We seldom get salty roads here. Most of my driving is local and up to 4 or 5k miles a year. I easily get about 50 MPGs with my car.
