Installing a New Air Filter (K&N)

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.

I see this was posted back in April. What performance differences have you noticed over the stock filter?

after the dealership failed to properly reinstall my air box (sucking in straight unfiltered air)... there was quite an improvement in power! so I'd assume the K&N would be an improvement. It's hard to believe that there is so much untapped power there. BTW, it threw an engine code by letting that much air in. I don't know if a cold air setup would throw it off that much

Great vehicle backed by lackluster dealerships

I had a K&N filter for my PtCruiser.

I loved it

I can't get over how cheap the Jeep ones are

I'll be getting one of these when it is time to change my stock filter

just my 2 cents sense i work at a Dealer// do not put the K@N sticker on you air filter box and keep the stock air filter. Change back to the stock air filter if you make a visit to the dealer because if they see a K@N air filter they just might cancel your warranty esp. if the concern is emission related like a check engine light. just my 2 cents.

might be wrong, but putting a k&n air filter will not void your warranty - as far as my dealer says





No More Jeep....

Not to sound like a Dink but this is my .02
your dealer ship sounds stupid, My dealer sells all after market products. Lights, rims, tires. exhausts and intakes. besides a k&n air filter meets and exceeds SAE standards. its ok thats like saying you can only put mobil 1 oil in your car, not ESSO synthetic oil, They made in the same facility or saying you can only but wrangler SR-As as replacemnts and nothing else

I have Moabs wrapped in 235/60/16 yokohama Geolanders magnaflow exhaust, aem intake, and they havn question any thing about my vehicle.

stupid is , stupid does. quote. Forest Gump.. lol

i put my k@n in today and it was easy-r to just take the whole air box out and swap filters then doing it in the engine bay area.. might just be mental but seems the engine reved up better.

im not saying all dealers will give you gripe over a mod. but it has been known to happen at some dealers. better safe then sorry.

Be careful with K&N filters. I know they have a big following and lots of fans and I don't want to be brand bashing but be careful. I have used every type of K&N from regular replacements to conical types and have had my problems with them. They do breathe better, that really can't be argued - just remember what a filter is designed to do. On my old Cherokee (88), I never had a dirty throttle body until after the K&N install. The intake downwind of the filter had a lot of dirt and grit that was never there with the factory filter. When using a K&N on my grand cherokee, the rubber sides that hold it the box were too soft and it would frequently get dislodged allowing zero filtration at all. I called K&N and emailed them about my findings, and you will love the answer. They said to be sure to use a pre-filter in dusty conditions as the filter isn't designed for certain fine particulates in extreme conditions. So, as a current non K&N believer, I just offer my "be careful" recommendation. Check for dirt and grit behind the filter often and make sure it stays seated correctly. You have to love a filter designed to breathe better, but at the cost of poor filtration? That is up to you.

09' Smurf Blue Patriot Sport, FD1, CVTII auto stick, yes essentials, 26E, and wheel and tire package. 01' Ram 4x4 with the Cummins. And our 62' Willys Jeep Wagon just to remind the Patriot that it's not a real Jeep.

I started using K&N filters in my Motocross bikes 30 years ago. I always sealed the filter to the airbox with a thin bead of grease. Never had one leak dirt. Now, water is a different thing altogether. If you are running in a wet environment, be forewarned. The K&N is next to useless. That being said, I'm putting the K&N CAI system on mine this summer. The filter, or better, the CAI are the most bang for the buck for a performance increase.
