For all information on the differences in Zip tubes, check out the following link compliments of dRock

Since the 2004 PI intake tube has been discontinued from Ford, we only have the 2006+ intake tubes (which will fit all 2005+ Crown Vics / Grand Marquis and Town Cars) and the ADTR High Flow Intake tube (which will fit all 1996+ Crown Vics / Grand Marquis / Town Cars)  Both parts can be found in our Intake section on our shopping cart
