K&N has it

[Lindyrect]

It's official. K&N has an air filter for the CX-9. (guitar)
Good luck finding it at the auto store. I checked four yesterday to no avail.

$52.95!! Guess forgot since the last time I bought one. I'll have to drink a few less 12 packs to buy it. LOL.

[l-miwa]

They are available for $38.50 with free shipping from http://www.autoanything.com

[Lindyrect]

autoanything has the 3.7L v6 filter selection and does not allow 3.5L for selection. I'm sure there is no difference, but they do not list the part #.

Mine came from weathertech today. Just installed it..........5 minutes max.

K&N lists the 33-2395. Is there any diff in that and the 2295??

I would assume if the K&N part number is different the filter is different. I do not see them making the same filter with two different part numbers.

Wrong filter--that one fits a Chrysler!

Their dropdowns show a 3.7L for 2007, which obviously is incorrect. When you select it and look at the actual order, it lists the correct K&N part number.

For those of you that bought the filter and installed it, how does it work for you? Any noticeable performance?

I have installed mine. I really haven't driven it enough yet to notice any performance difference. What I am hoping it will squeeze a couple extra MPG out of it.

[FikseRxSeven]

anyone that bought it seen any increases in gas mileage yet?

[FikseRxSeven]

any feedback on the filter yet?

[l-miwa]

Without a rigorous (dyno) test, you're going to have a hard time determining exactly what performance / mileage improvement you get from a K&N filter.

I got mine simply because it works at least as well as the OEM filter and I don't have to replace it all the time.

[jabba]

Don't K&N filters have to be re-oiled once in a while? Not sure about the one for the CX-9, but the one for my Audi requires it to be lightly oiled, which can be an issue if you clean it out and put too much oil back in (excess oil can ruin the mass air flow sensor)

[WaxiP5]

K&N filters are oiled I believe. I am afraid to use one as there have been instances of the MAF getting dirty from excess oil. For my Subie, Blitz which is dry.

[jabba]

I haven't put a K&N in my Audi for that reason. Don't really need the extra HP (if any) anyways, since I upgraded the turbos and had it custom tuned, he he he! Too bad the CX-9 doesn't come with a turbo or two...

[Force-1]

I have used K&N air filters in my last 8 new vehicles, and have never had a MAF problem. This typically occurs when the user puts too much oil on the filter when cleaning it. I don't have this problem as I just buy a new one instead of cleaning it. New filters are oiled just right at the factory. I don't really consider it a cost issue since you can go 25-50K miles before cleaning.

I've had a K&N in our Volvo 850 for over 200K miles. I've cleaned and re-oiled it a number of times with no issues so far.

[Lindyrect]

Same here. My Jetta had a K&N and I oiled it 2X. Never had a MAF issue.

[sp535]

do you have to change it per mile or per time passed?
Kindly advise.

From the K&N site:

How often do I need to clean my K&N air filter?

If you have not experienced a decrease in mileage or engine performance, chances are your filter is fine and does not yet need cleaning. To be more specific, the filter does not require cleaning if you can still see the wire screen on the entire air filter regardless of how dirty it may appear. When the screen is no longer visible some place on the filter, it is time to clean it. When used in normal paved road, street or highway conditions, our replacement air filters that fit in the factory air box should require cleaning every 50,000 miles and our large conical filters on an intake system should require cleaning every 100,000 miles. When used in dusty or off-road environments, our filters will require cleaning more often. We recommend that you visually inspect your filter once every 25,000 miles to determine if the screen is still visible.

I doubt that K&N filters improve your MPG.
More air into the engine triggers more fuel into it as well.
As a result, more torque (x RPM => more power).
In the meantime, less MPG.

[CX9 SportOwner]

we added 1 mpg to our cr-v with a K&N. and boosted the low end power noticibly

A filter cannot 'allow more air' into an engine. The amount of air brought in is fixed and is determined by the displacement of the engine. A low restriction air filter will improve MPG and HP, by letting the air into the engine with less vacuum. Less engine work is being used to take in air, therefore more is available to produce power.

[ceric]

Just read thru the testimonials on the K&N site.
When I thought about the K&N power benefit, I have never thought about the
MPG benefit. It is funny that they have not been promoting the MPG gain
more than the power gain.
I am very tempted to try it out now.
Thanks for correcting my wrong perception.

[mainerunr]

I think K&N's power benefits tend to be overstated. Any newer vehicle with a decently designed intake system and a large filter area should perform just as well (for instance, the nissan frontier actually dynoes 1hp LESS with the K&N and zero difference in mpg's).

If you have other reasons, drop ins can be good but looking for power or mpg's from them will probably leave you disappointed (or living with a placebo effect).

[Mazda Newbie]

Anyone with the K&N seeing an MPG improvement, even slightly?

[MacMaster]

My friend told me k&n filter improved the mpg lil bit more like 1 or 2 mpg, thats what he said tho, im getting mine tomorrow i ordered it yesterday, will let u know after testing it.

[ceric]

I have K&N on my CX9 for the past 5000 miles (put it on at 1000miles).
I have seen no effect on MPG. However, I like the way K&N allows the engine to
rev happier. So, it stays on.

[CX9 SportOwner]

Exactly, plus it lasts longer between maintenance, and then is just cleaned.

Yeah, it depends on specific brand, model and year.
For me, just bought a KN CAI for another vehicle, and well, has increased MPG significantly. Not only power, more acceleration and way better sound.

[Lindyrect]

I jst bought mine this past weekend. The original paper filter is coming out with 37k on it, but I did vaccum and blow it out once. I can't wait to see if there is any difference at all. Hoping it might change the intake/rev sound a bit. Bottom line is the filter will outlast the car.

Did you say 37K? What type of driving conditions [environment] do you typically experience? Isn't almost 40K with the same filter a stretch?

good luck.

[The-9]

any type of gauze filter has no advantages over a paper filter when new. In fact, it is almost time to replace the paper filter (15k) when the gauze starts to show it's benefits, which are longevity. Cold Air is what is needed and the thought of a filter giving gains over a new paper element is not factual.

I personally do not like gauze/oiled filters. Over oil them and they cause problems, under oil them and they let dirt through. Best bet is a quality filter like Wix

[Lindyrect]

Yes it is, but I vacuumed it out and blew it out w/ compressed air. Lazy maybe, but was trying to pay off a few bills before I bought the new filter. If I am not mistaken when I brought my vehicle in for service at the 7500k mark they might have changed it. Dunno, all I know now is that I can wash it out whenever I want now.

Don't believe the hype or scare of over-oiling. You have to be a complete tard to over-oil or soak the filter. You almost have to do it intentionally. Just read the manual that comes with the cleaning kit. Wait...did I say read the manual??? I might end up eating my words now.

[Touring9]

I've used K&N in my last few vehicles. There was a slight improvement, but not significant. The advantage with air flow is that they eliminate any possible weak link at the filter for flow restriction. The CX9 has a good sized filter, so I doubt there is much reduction in flow even with a paper filter.

The real advantage, though, is that you don't slowly lose performance as the filter gets dirty, like you do with a paper filter as it fills with dirt.
My cars are just as perky right before I clean the filter as they are right after.

Lindyrect is correct. It's virtually impossible to over oil a K&N. The membrane will only hold so much oil. Any excess oil simply won't stick. The only way to have too much is to hold the filter flat, spray it until it's drenched, and immediately put it in the air box. If the oil side is up, it will choke the air flow until is can be sucked through the filter. If it's down, the extra oil will run off and end up in the engine. Again, you'd have to do it deliberately.

[cccx9]

Yeah you gotta hate all that pesky filtering the paper filters accomplish :)

[Touring9]

Wow. Having owned two CX9s now, I thought I'd come here and offer my experiences and know how.

Too bad every time someone gives some sound advice, all the wannabe knowitalls have to chime in and discredit that advice just to massage their own ego.

I think I'm done with this site. Sad

[Lindyrect]

I know what you mean. There are a few flamers here, you know what I mean, that like to banter between themselves. I believe that unless your post has some relevant help, you need to keep it to yourself or else the MOD should impose punitive actions.

[cccx9]

Oh you're kidding right? I'm sorry I was so harsh. MODS please punish me.

Any filter will clog over time. Doesn't matter what the media is. A K&N will not clog as fast because it doesn't filter as good as paper. Yes you get more air flow with the K&N but there is always a trade off.

Sorry I wasn't trying to bash you. I just thought the way you put it was misleading.
