Yes, it keeps the bugs out. I removed the screening over the headlamps, though,
to make it easier to wipe the headlamps clean, when needed.

Depends upon whether or not the screening is original. I had the torn screening
in my Westy's mask (a.k.a. bra) replaced by a local auto upholstery shop a
couple of years ago. Although the replacement screening wasn't as "open" as the
original, I paid the man and went happily on my way. A few months later, while
travelling though Montana in 100 F temperatures, the van began to run hotter
than usual. Something fishy here, I thought, so I pulled over, removed the mask
and continued on my way. From thereon, the van ran at normal temperatures. I've
since replaced the screen (again) but this time with a more "open" mesh.
