Step 1
.....................and building a sheet metal barrier between the air intake and the engine. I have thought of also experimenting with an air scoop or several well placed holes behind the grill to force/direct outside air around the air filter.
For my 3.0 I plumbed a 3" flexible hose from below the headlight into the inner fender, seems to work well enough, not as well as w/the headlight out, but much better than before I isolated the filter from the engine bay air.
I yanked the upper intake manifold off this last weekend and I am polishing the inside as far back as I can reach. I know this is a very small thing but looking at several upper intakes it should help in the long run by eliminating places for the nasty oil/dirt/gunk to build up. Has anyone had experience polishing a upper intake that can tell me how to get inside the individual tubes? I can get a dremmel and sand paper about an inch in and thats about all.
You likely wont be able to polish the intake runners smooth at home, but you can smooth them out some by using a flexible hone
