You have 2 options:

1. Install Vinyl Screen (Gutter guard from Home Depot for a few $).
I posted info on Step 12 here:

2. Get rid of the air duct (that goes from the body of the car ---> alternator itself).
My Honda and Volvo have no air ducts for alternator.

The air duct seems like a nice idea (if it works as intended). Unfortunately, leaves, debris fly in there, making it worse than w/o the air duct.
