I'm not really interested in rehashing a filter flamewar that has been held countless times in innumerable fora.

What I *am* interested in is obtaining a filter that's not built out of ignominy and failure. I mean, I just had two filters delivered: one to replace the cacked factory one and one to replace the replacement when *it* fails in 6 months.

There has to be a better way, without risking lines of repair sealant dislodging and getting blown into the engine. Read: I don't want to use sealants for gasket repair.

Re: Check your air filter

Same here. I want an OEM filter that DOESN'T crack! I repaired my original filter after exhausting my search for a replacement and needing to leave for a trip. No parts stores carried them. My dealer had one shipped in while I was gone and I installed it when I returned home. Gluing my cracked OEM filter was an emergency manuever!

BTW...an oiled cotton gauze drop-in filter would have been welcome at that point! Anything beats a filter with a broken seal.

Here is an interesting unbiased test using precise methods:
K&N Air Filter Review - Debunking the Myths (and why OEM is better)
I'd hardly call an article that starts with a diatribe from the author using phrases like "the reason I started this CRUSADE" - unbiased.

The purpose of oiling a cotton gauze filter is so that the filter media ATTRACTS some fine dirt/dust. That dirt/dust in-turn effectively becomes part of the filter. If you clean the filter too often or don't oil it enough for fear of screwing up your MAF sensor, then yes, you're letting fine particles through.

If you RTFM and follow K&N's directions, you have a good-quality filter that you never have to replace.

Either way, as you state, it's better than the factory filter in this case as it doesn't have gaping holes in the rubber seal...

To each their own, though. I'll continue to use K&N, and y'all continue to do whatever floats your boat. It's your money, after all.

Re: Check your air filter

My filter is just fine after 10k and me opening it up and checking it 3 times.
OK, so the filter seal has to seat properly in the grooves around the bottom of the airbox and you have to line up the 3 "tongues" in the back of the airbox top correctly and then EASE down the top onto the orange rubber seal.

I can see folks (either building the airbox/car or checking the filter!) doing it quickly and tearing the filter orange rubber seal.

Our Kia uses a similar square filter with the same orange rubber seal around it. I've changed it twice and not had an issue, and you have to seat the orange rubber seal correctly in the groove on that as well.

Just sayin', not critiquing anyones filter changing....

Also, I have used a K&N in the past but way prefer the smaller micron filtering of a stock paper filter.

Living in a dusty climate makes it necessary to use the BEST possible filtering method for all my vehicles and K&N is simply NOT the best. Yes, they offer a "million mile warranty", big deal. I want and need to use the BEST oil and BEST filters in all my vehicles and, again, K&N air filters are NOT the best.

YMMV and you spends your money and takes your choice !

Re: Check your air filter

Checked mine today. Sure enough, it is cracked on three sides. About 10% of the cracks are deep enough to go all the way thru the orange rubber material and potentially let dust in. I smell a recall or TSB coming.....

At work we use oiled gauze air cleaners on our high performance diesel marine engines in yachts. But any diesel engine that sell for land based applications, especially those that operate in dusty conditions, use paper element filter media. That's a no-brainer in my opinion.

Re: Check your air filter

I see the urge to engage in the same tired debate is too strong for some to withstand.

However, on topic: today I replaced my OEM FailFilter with a replacement OEM FailFilter. In the process I determined why it is so difficult to reseat the air box and, concomitantly, how to properly reassemble the air box. Maybe this was obvious to everyone else, but I certainly had some difficulty so I thought I would share.

Those three tabs on the back of the housing are a major pain to get engaged. I was concerned that if I pushed hard it might stress this filter's gasket which is apparently made out of the hopes and dreams of orphans. So, I spent some time with the cacked factory filter as a trial run of reseating the box and relatching it.

The issue is the fuse box that is immediately superior and posterior to the air box. When you try to push the air box tabs into the slots the air box housing is abutting the fuse box and preventing the tabs from moving posteriorly. Therefore, they do not want to go in.
Solution: reach down with your left hand and pull the lower part of the air box anteriorly, toward the front of the vehicle. This will allow the tabs to enter the slots without requiring much effort, because you avoid pushing the air box housing against the fuse box.

Protip 1: ensure the lateral air box clamp (the one on the right as you are facing the vehicle) remains in the open state. It really likes to bounce back to the closed state and prevent you from making the seal. If that happens, you basically have to start over by removing the top of the air box in order to get the thing back open.

Protip 2: I suggest getting comfortable with the procedure on the old filter, and get to the point where you can run through the entire process successfully twice before you risk damaging the new filter's delicate flower of a gasket.
Finally, I disconnected the intake hose in order to give myself more freedom of movement, but I'm not certain that's necessary as long as you pull the lower air box forward. I'm sure you'll find out for yourself if you do some trial runs on the bad filter.

Anyway, I hope someone else finds this useful in the future.

Didn't know we needed your permission. Another alternative would be for you to just skim over the content you are tired of reading about?

Good tips however. Thanks for sharing. In my opinion there is something bigger going on due to the fact that many people's are cracking on three or four sides, not just the side with the tabs on it. I notice that the filter is basically hanging in the air box supported solely by the orange gasket material. I suspect if one could somehow put a high speed camera in the airbox we'd see the filter bouncing up and down. Maybe from engine vibrations, road vibrations, or maybe from an occasional surge of air coming back out of the airbox when the throttle is chopped. I dunno. Something's fishy and I bet it is design related, not improper installation.

Re: Check your air filter

I too have the cracked filter gasket but it gets even better. When the dealer ordered replacement filter showed up the gasket was cracked before they could even install it. They ordered three more just to make sure they got a good one to install. Be sure to check your "NEW" filter before install. My dealer has elevated this concern to the dealer representative.

Re: Check your air filter

Mine was replaced yesterday, (I had to drive home from my last major trip with the old one repaired with silicone.)

Thought I'd check it last night after picking the car up from the dealer......
Hmmm, new one is cracked on two sides already. Obviously a COMPLETELY faulty batch, hopeless.
I will have to look for another brand as the genuine one is obviously a waste of time.

Re: Check your air filter

Wow. New filters are cracked while still in the bag. How pathetic. $7000 engines put at risk with cheap filters that probably cost Jeep $5. The new spare I bought from the dealer was batch "AA" which I was told is the original batch. So it doesn't sound like the ones in the parts system have been updated yet. I wonder if they'll let me return it when they come out with an updated filter later.
