I removed the under-engine plastic shield to change my axles, and left it off for the test driving.

I had noticed incredibly high underhood temperatures of the S60 here in Texas, but the dealer said that it was required for mainly noise reduction, and it contributes to fuel economy by keeping the airflow stable under the car, though at only 23mpg for my T5, I can't believe it helps economy meaningfully.

When I got home from the drive, I opened the hood and was amazed that no wave of hot air greeted me as before, and I could easily touch certain metal components that I couldn't get near when the cover had been installed.

It would seem lower underhood temps would increase the life of especially rubber components like belts and hoses.

Is there any downside to leaving it off? Does its absence effect airflow for proper road cooling in a negative way? I really don't see how it helps with water splashing up or anything like that.
