Why the plastic cover over the bottom of engine?

I had a plastic cover under mine... removed it. I haven't noticed a difference. At least the one on an Evo has separate pieces so you can get to various places (like there's a removable piece under the oil filter for that purpose).

Ditto on the aero effect, but what some people fail to remember is that the cover is commonly called a "splash guard." Not only will it improve the aerodynamics of the car, it will also prevent unwanted debri or pests from entering the engine bay (if conceived correctly).

I do have to agree, however, that Nissan went into overkill mode with the 16 bolts and 3 clips (which will probably be broken by most after the first oil change). It's a pain.

At least the Z uses bolts. Evos got a shitload of those crappy plastic screw clips that either don't unscrew or break.

Yeah, What the heck. Those engineers probably didn't know what they were doing anyway. Pull off the spoiler and the aero flaps in front of the wheels too..

He'll notice a difference when that flimsy-looking oil pan is shot or a piece of debri blows a hole through the filter, or knocks it off entirely.

Aero flaps?

The spoiler makes a HUGE difference. I've driven Evos with and without, and it's VERY noticeable.

Anyways, on an Evo, it's called a splash guard. Doesn't do too much IMO since it never gets dirty under there.
