The owner's manual calls for a changeout every 30,000 miles or 3 years, whichever comes first. That doesn't make a lot of sense to me. These off-road vehicles suck in a lot of dust off-road and plenty of dust on-road too in a dusty state like Arizona. And since air filters are cheap, and the installation easy, I thought I'd go ahead, invest a few dollars and minutes and change mine even though I am only about half-way to the 30,000 mile mark.
The STP filter cost me $13.89 plus tax at Auto Zone.
Well, the installation used to be easy on Jeeps: unsnap four clips with your fingers, lift up the plastic air box hood, remove old filter, insert new, reconnect clips. No tools needed.
So I unsnapped the four clips, but the hood wouldn't come off. So I got a flashlight and looked for a fifth clip. Didn't find one. Now I am sweating like a pig and cursing the recalcitrance of matter. Why is this simple job proving to be difficult?
To the Internet! One video was useless, and so was the Jeep Forum, but then I found this video in which the secret is revealed.
