I watched my pressures last weekend and at 8,000 and 9,000 ft I had a 
1.3" increase in manifold pressure over what the outside atmosphere 
should have been. I was traveling at 160 kts indicated and between 180 
and 190 kts true.

I have a downdraft carburetor and had an RV-4 air filter put on. This 
oval air filter gives me filtration all of the time. I also feel that 
the air filter has helped the air enter the carburetor with less 
turbulence.

Oh, and by the way, both fate and God also help us out of icing 
conditions.
