Air Filter

I installed the K&N over the weekend. Was a bit of a tighter fit to close the airbox, but got a good seal. Make sure the filter is sitting in place well, especially to the bottom of the airbox. Anyone else get the K&N or the Mopar (Caliber) air filter? Curious to see your perfomance impressions or MPG changes if at all.

better yet a dyno chart!

Guys I don't want to rain on the parade but I am really not a fan of K&N air filters in a car that you drive every day so I thought I'd add my 2C's about K&N: Stricktly speaking in order to get more air flow through the filter, the holes in the filter media need to be large enough so as to not "upset & restrict" the flow path. This alone increases the flow of air between the two sides of the filter. Pretty simple right?

With K&N, these holes are nice and square and pretty large when you compare to a paper element. This is where the claim of "more power" comes from. But of course if those big holes are letting in more air they are also letting in more fine particles of dust and debris.

Now most of the people on this board seem really smart about engines so it's safe to assume that no one has ever seen gigantic chunks of dirt floating in the air while you drive down the parkway, road or track, right? What we do see is dust and a lot of it. A paper filter stops this material from entering your I.C.E. where as a K&N will just let it pass through.

Overtime the passthrough of this dust will wearout seals, rings and valve seats. Not to mention "junk up" any and all sensors with slimy crud that requires seafoam to clean out. K&N is a horrible filter for the everyday car. Racecars or cars that have motors that are constantly being rebuilt is a different topic all together


Also, K&N can claim a 4hp increase in total power on the box, but how many people drive on the road with the engine at redline to observe that increased benefit of performance? And for what, the cost of your engine? Too many people buy into marketing of this filter.

Stick with a paper filter - your engine and wallet will thank you in a couple years. Again sorry to be negative about this
 
Rather spend the $7 or so

Rather get a new paper filter every so often,
than trying to keep a reuseable filter clean,

no matter what the claim,
filters gets old, dirty, and doesnt compare to a new filter
 
Sooooooooooooo...........

Anyone wanna buy a NIB K&N Air Filter for a 2.4 Patriot?


:eek:

Have you compared these holes? I thought that the enhanced free air flow was acheived by oiling the fabric and using a better fabric (not cheap paper).
I will check it out next time at the Auto Parts store.

I did used K & N air filter before (Dodge Stealth R/T twin turbo), the car seemed to breath better, but as noted, somewhat noticeable only at high RPM. I did not check gaz mileage improvement at the time.
 
Here's an informative link http://www.bobistheoilguy.com/airfilter/airtest1.htm. Personally, I have used k&N air filters w/ air intake kit in my 97 Wrangler (100K+ miles), and now in my 07 Compass, and love the improvrment in throttle response and acceleration- especially in the 5-speed compass which used to be sluggish off the line before the k&N intake.
My 10 cents...
BTW, I don't think you'll see much improvement just with the K&N filter in the old airbox.
 
Thanks for the links. The Bob Oil Guy is a nice one.

The second one over at jeepforums they are talking about the cold air intake set up as opposed to the air filter spoken of here.

Just as interesting tho since I know many are waiting with baited breath for a Patriot version to be verified.


Cheers,

If Amsoil has an EaA filter...I would try that. The replacement EaA201 for the Liberty had 2X the surface area as stock...deeper pleats and many more of them.
Hi Darby,

When you use the Vehicle match application on the Amsoil site it only lists a WIX 49192 air filter for the Patriot. Does not mention anything about an EaA model.

Am I correct in viewing the page and interrupting what you say that they are 2 different versions? WIX and EaA?

thanks
Jim
 
Answering my own question.

yes, they are 2 different models and Amsoil doesn't have an Ea model listed for the Patriot yet.
 
Me again.

Bob's air filter test that was lonked to here backs up what was said re: the K&N.

You will get better air flow with a K&N but also allow more debris thru.

Everything ha s a trade off.

2 points to make:

1. the cold air kit will usually be a oiled gauze cone or a foam filter, so comparisons to the gauze/foam panel filters should be similar as far as filtration.

2. Flow and Power are directly related, and have trade-offs. Suprising to me how both paper and gauze seem to let through a LOT of particles!

For now I am sticking to the gauze since I like the throttle response...I will let you know if any gremlins come up. For sure be careful not to over-oil!
 
By all means don't take my post like I'd trying to come off all preachy. I just feel that people don't consider the trade off when they go looking for more power and better SOTP's feelings.

K&N fails to tell you that you'll be sucking in more dust and most people won't notice it so I like to state it.
 
I've had a K&N filter on my Wrangler for over 110k, so its been sucking in a lot of dust, and it still runs perfect.

But who knows? I've seen arguments on both sides that make sense, but unless you are trying to make an engine last 300k+, I don't think there is too much to worry about.
 
Thought I would throw my .02 for shiz and giggles. Mopar offers there own branded CAI and neither the K&N nor the Mopar version void the warranty (i know if the oil from either messed up a sensor it would be on the customer to pay for it). That said, the lifetime powertrain warranty should handle any problems you may have at 150,000 miles from the extra particulate matter. Am I right???
