Here is a quick post on how to change your air filter in your Jeep Patriot. This is a very simple task and most people probably do know how this is done, but for the few who don't here it is. Note: The pictures are not great as they were taken from my cell phone, but they will do. I went with a K&N Air Filter Part # 33-2362.
After you get a new air filter of your choice and open the hood it's time to find the location of the air box. The air box is on the right hand side of the engine.
1 Remove the battery cover/ Air Intake.
This is done by turning the 2 plastic fasteners counter clockwise and then pulling the unit up and then sliding it towards you.
2 Now that the battery cover and intake are off now you can open up the air box by lifting the 2 metal prongs up.
3 Now you need to crack open the air box to get the used filter out.
Do this by separating the tops of the 2 sides of the air box and pulling up on the left side of the air box. As you can see only the left side of the air box needs to come up.
4 Pull the old filter out and put in the new filter.
In my case I used a K&N air filter so it will never have to be changed, only cleaned. Also the K&N filter came pre oiled. It helps if you put the new air filter in the right hand side of the airbox and then put down the left side of the air box.
5 Now simply snap together the air box.
Make sure you snap the bottom part of the left hand side of the air box first and then align the top part of the air box.
6 Assemble the air intake/battery cover.
Slide in and gently set down and then put in the smaller piece that has the 2 plastic fasteners. Align then and turn the 2 fasteners clockwise.
If you do go with the K&N reusable air filter make sure you place the "DO NOT DISCARD" sticker somewhere near the air box so the idiots at the Jiffy Quick Lube place don't sell your wife an overpriced Fram air filter.
