Ok all, I am TC from Va. I want a helix trottle body spacer for my Mark. I see them listed for the 97-03 Navigators but that is it. Does the Navigator have the 62MM or 65MM one? I am assuming my car has the 62MM one because it is the base or non LSC Mark. Is that right? Someone let me know. Also, let me know how to get the air silencer thing gone. I am assuming I can get a few horses from removing the air silencer right? Thank all in advance!
