engine side shrouds

[cannon man]

both sides of engine have a fiberglass cloth that goes from outside of frame rail to underside of floor. full front to rear of area looking over the tires. can't see engine at all. whats it for? better air flow over engine? keep water spray from tires off of engine? protect engine during undercoating? do they stay or should i remove them?
