Want more power out of your FJ Cruiser?  We did too!  When we
bought ours, one of our first upgrades was the high flow, washable
K&N Air Filter.  This filter is an affordable upgrade, a
K&N air filter. This is a washable cotton gauze air filter. This is
the last air filter you will ever have to buy. This is a custom
made filter that will fit your factory air box perfectly. You can read
