"Out of the 27 vehicles I've owned, I've either purchased a K&N filter or the whole intake kit for each one. I am now getting between 40 city -70 highway miles more per tank of gas. The power from these has always been remarkable for me.It would've been 5 stars, but a little loud." —Jonathan V from Spring Hill, FL bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Toyota Sequoia.
