"Although the K&N filter I purchased for My 2008 Highlander fit perfectly, it was slightly thicker than the OEM, thus causing a few issues when being installed.This is not a K&N problem, but it seems that Auto manufacturers are basically very lax concerning placement of simple, user-replaceable parts on their vehicles...I was yearning for the old circular air filters that used to be replaced with a simple wing nut." —Donald M from Amesbury, MA bought a K&N Air Filters for a 2008 Toyota Highlander.
"Have heard that a K&N filter would improve mpg and increase horse power thru easier airflow. Thought I would give it a try in my Toyota Highlander. Installation was easy and the K&N filter far surpasses the quality of the OEM filter I removed. Car seems to respond quicker and run easier but still too early to see if mpg has been improved. Will purchase another for my Chevy." —Alan W from Piedmont, OK bought a K&N Air Filters for a 2008 Toyota Highlander.
"I use K&N filters in all my vehicles. It is an easy modification that pays for itself in short order. It is generally about a 2 mpg change in fuel consumption plus a little extra when trying to get over a hill with the boat in tow. I would suggest one in any application." —Tom C from Fenton, MO bought a K&N Air Filters for a 2008 Toyota Highlander.
