Hi im new to the aspens and wanted to know would making my own open cone intake increase and performance or MPG on my aspen? we did this to our last car but now we don't know would it make a differ in the aspen? its a 2007 Chrysler aspen 4.7 limited RWD.

You know taking out the stock air box and putting on a cone filter. would it increase HP or anything something noticeable?
