"I installed the intake to get some more HP out of my 4.6L V-8. I use my car for both general use and emergency calls because I am search and rescue in the Coast Gaurd Aux. The intake took 20 minutes to install because I had all the right tools, and the rear drive panther platforms are easy to work on. If your looking for a little kick this will be the right product for you.AL" —Alexander W from Mount Pleasant, SC bought an aFe Cold Air Intakes for a 2011 Mercury Grand Marquis.
