Bingo! These were a big thing when I first got my 04 Titan but I never saw anything definitive enough to make me shell out the bucks. Some say it worked some say it didn't. From my Talley the people who were running an aftermarket CAI (Cold Air Intake) and exhaust are the ones who said they saw the most increase but nothing even close to 2 to 4 MPG's, more like .5 to 1 and a change in humidity, driving style, air temp, tire pressure or bad math skills can give you that.
The same goes for the grounding kits. Let me tell you, if the installation of pretty wires makes your FJ run better it was because you had a bad ground connection in the beginning and not the pretty wires.
