[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 #.

(omg)

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

AJ USA (http://www.ajusa.com/cgi-bin/stores/details?vendor_code=KNF&ajr_part_number=KNF%2033-2395&source=lookup) lists it for the 3.5 and 3.7, $42.50 delivered.

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.

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).

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.
