Guys, are these cars supposed to have underbody diffusers and/or plastic to cover up the guts like exhaust components and such? (Similar to the plastic that you take off to change oil/filter).

I could've sworn it has it based on my initial inspection of the car, i just got it back from the shop for a Cat Converter and A/C compressor change, and the bottom is bare.

On a similar note, how do you know if you have 4WAS just by looking?

Thanks!

 

Only the engine are is covered.

You can tell you have 4WAS by the large actuator near the differential:
