hey guys i just discovered that the previous owner installed a K&N filter on my 01 TJ. So instead of buying a new air filter i went a head and purchased the recharge kit from K&N. Wow this air filter thing turned into an hour long process of spraying the cleaner, letting it sit then rinsing it off (repeating) and then i had to let it dry for over an hour, then spray it with oil, then let that sit for 20min. Is all of this worth it? It seems that buying a good air filter and tossing it when it get dirty would be much easier. What brand of filter do you guys use?
