Its on their for a purpose to vent the rain in layer instead of falling on one desired spot, leave it on when it is going to rain, unless you are sitting in a garage.

 

Pardon my ignorance, but what purpose would removing the hood screen serve?

 

looks and helps get rid of heat soak when in traffic, but mostly for looks..

 

just removed mine, and I have to say I think it looks pretty trick. this has gotten me wanting to do a little clean-up in the engine bay now...has anyone else got the rust around the bolts on the heat shield and manifold? is there anything you can do about it - paint them or something?

 

it is simple dude no worries

 

everyone gets it.
to fix: go aftermarket

 

Channels water so it drains better - less corrosion in rain

Hood is shaped in such a way that air flows over the top creating negative pressure over the vents which slightly help draw air from the bottom and front.

May also serve to draw heat away from the painted surfaces on the hood. Prolonged heat decreases the durability of finishes.

Bottom line: Other than water drainage and looks, doesnt really serve any real purpose. If you have a nice tubular to view than show it off, just resecure the screws and clips to keep the other stuff from flapping in the wind.

 

That's what I do too. Unless I know it's going to be raining like a bi*ch then I'll put it back in. Looks hard with it out though
