Yeah, the stock setup can be annoying, but its going to be a better option for the engine. If you're missing the heat shields on the rubber mounts then you'll certainly have to change them more often.

This is from post #6 of this thread: I did a test where I drove around with a Thermometer and a temp probe about where the new Air Filter setup was going to be. What I found out was that while when you were stopped the under the hood air temp would go up to like 160+ degrees very soon after you start moving the under the hood temp dropped to with in 5-10 degrees of the outside temp.
My conclusion was that when the under the hood temp rose when I was stopped at idle it made no possible difference in performance.
Once the Car was moving the under the hood temp drooped fast enough and low enough that I don't believe there is any difference in performance. Meaning that having the Air Filter drawing the Air from under the hood had no detrimental effect.
During the winter idling at an intersection and having the under the hood temp rise 160 degree + air and drawing in that hot air is actually a added bonus. In warm weather it makes no difference.
Once you move even at City traffic speeds the under the hood temp plunges close to the out side temp. At least it does that where my Air Filter Ended up.
