What's Your Engine Temp?

[Lil bastard]

Don't know as if I'd want to remove or drill any holes into the plastic covers under the car, or remove them.

Aside from playing a role in the car's aerodynamics (which probably have little effect at legal speeds anyway), these covers are designed to direct airflow to the proper places, ie around the engine bay.

The primary source of cooling for the engine is the oil and the coolant, not ambient air, probably like 95%.

But, consider that the only source for cooling ancillaries like the alternator, AC compressor, drive belt pulleys and tensioners is the airflow through the engine bay. Loosing a few degrees on the temp gauge (which is nonetheless operating in the OK range) may not be worth compromising the service life of these components.
