Those ducts will work much better and would be preferred...but being that they are 5.5" tall they will not fit in the same location without some cutting/fab to get them in there as there is only about 4 to 4.5" of space.
This one that is 6" wide and 3.5" would fit better in there: https://www.pegasusautoracing.com/pr...p?Product=3623
and I will be changing over to this one during the winter utilizing the same location
FYI: You can piece together a kit from Pegasus for much cheaper than the kit from Jegs
I did not get mine stuff from here, but I have used them in the past..
