Cold air intake vs. K&N Air filters for Weber DCOE 45s

[z boy mn]

Interesting results on the under-hood temps. It makes sense that almost all the heat will get sucked away when you're at speed. And, I suppose that when you're at a stop light, you don't need all the extra HP the colder air might make. ;-)

I'm leaning toward trying to adjust the box I have now, but after seeing the one made out of a valve cover gasket, I'm thinking that would be cool. Even better might be to cut off the top and put in plexiglass. I wonder if I can find a valve cover somewhere! :-)
