2005 4.6 G. Marquis intake or performance parts

Discussion in 'Other Auto Tech' started by 7991LXnSHO, Jan 27, 2013.

  1. My G. Marquis is apparently drive by wire. Is there a throttle body upgrade for this car? The MAF and air box swap from an suv does not sound worth the time. Are there other performance parts for this 4.6 and where do I get, them?
  2. Is this a dead discussion group???
