Engine cover necessary?
Is there really any purpose to the plastic engine cover? I'm getting really exhausted with taking it off and putting it back on everytime that I open the hood, and I think I have decided I like the look of the uncovered engine compartment better anyway. I am pretty sure that it is just cosmetic, but with all the other quirks of the rotary, I want to be sure before I remove it for good.

He's as bad as Can
Past threads on this matter have come up with airflow in the engine compartment, as the main reason it exists, looks second. The vents in the side are there fro a reason; the engine cover helps direct the air over the motor and out those vents. I have run my 8 with and without and only notice a little more noise. If I lived in a hot climate I might leave it one all the time.

personally, I think Mazda did it b/c the engine looks so small, someone who doesn't know a whole lot about engines my think the engine is too dinky for them, just a thougt.

Well, someone did measure underhood temps with and without, and they were hotter without the cover. Is the difference worth it? I guess that's anybody's call, but I don't think Mazda would have paid the money to add it if it didn't serve some purpose.
Personally, I would take it out if I had a good reason to do so (i.e. I had a strut tower brace that wouldn't fit it, or a supercharger that was in the way (I wish!) but other than that, its really not hard enough to remove for me to worry about it.

if it is for under hood temps at all I wouldn't remove it. It could be acting like the under hood thermal blanket on the hood. If the temps get too hot it could damage the paint prematurely.
Id like to know where the temp sensor was placed when they did the test. If it was directly over where the engine cover use to be then it makes sense why the temps went up.
