Well I HEAVILY weighed the pros and cons of adding the K&N air filter, and went ahead and tried it.

I have no mpg reports yet, and I will let you know of particulate matter in about 15,000 miles, but one thing it did add was a VERY nice, MUCH needed punch to the CVT transmission.

It really added some zing where the Patriot needs it most, from zero to 40.
Especially right off of the line.

So if you have a lot of traffic darting to do, you might want to consider adding one.

Cheers,
Jim

Wow, I've got the 5 speed wonder if it would help MPG?????
Have you heard of a performance 'Chip" for the Patriot????

Thanks for the tip!

If we go with the CVT, that will definitely be on my wish list.

Fortunately, I make my own schedule with work so when I don't work from home, I'm in the office very early in the morning and out by early afternoon so I miss the traffic, but the people here can't drive for $hi+... when it starts to rain or there's even just a fender bender, traffic goes crazy. It's a total crock but, meh, what can you do? I just crank the tunes and kick back until it's over. :p

What was the part number for your filter? I am having a hard time finding one that actually says it will fit an 08 Patriot.

Thanks!

Just go to K&N.com, its there. Soon there will actually be a full blown air intake system, but I would not recommend it for those that have the CVT2L because of the higher positioned intake in case of water fording.

See any differance in MPG ?

Great info as usual Jimmy! :smiley_thumbs_up:

Thanks King!

See any differance in MPG ?

Not really. My mileage is up, but it is also fall now so I have been running without A/C, so too many variables to point to the filter.

This is just my thoughts, but I don't think the filter really raises mpg.
At the K&N site, they specifically mention that they do not claim any mpg improvement.

And if I have this right, the filter allows more air in, correct? So that means your plugs run hotter and push harder. (?) Well wouldn't hotter sparking plugs actually be using MORE gas?

But my mileage is not down, and I have more punch, so I will claim , 'so far, so good'.

Jim

If an engine breaths easier, it's more efficient, or basically it runs better. So I'm 100 percent sure you're getting better fuel economy, and better performance, but the thing is it makes such a little difference that it's barely noticable.

It's just inhaling more air right?
Bigger holes in filter.

I guess I just have a hard time seeing how you get faster acceleration without the trade off of more gas being used.

same amount of gas injected but more O2 to burn it maybe...

OK, I see.

Three days ago I installed the K&N Filter and am very impressed. I received noticeably more power increase with this than when I added my custom Magnaflow exhaust. Although it is very preliminary, it looks like with the two changes I am getting almost 3 mpg increase, from 21 to 24 mpg.

I installed a K&N insert on my 2.0L the first week. I've used them with good success in previous vehicles. They don't make any difference, in my experience, in Toyotas, Hondas, or Mitsubishis. I wondered, though, since the engine is a 'Global' made by Chrysler, Mitsu, and some third mfg'r that there would be a difference. There is, indeed, with, as you mentioned, good kick starting acceleration. I believe I increased my mpg maybe by 2.

There is also a K&N cold box bolt-in for $250, but, horsepower increase is maybe 8-9 as I recall, and mpg increase minimal. Small payback for big investment. There is an installation .pdf guide out there somewhere. I don't mean to be vague, I just can't remember where I saw it.

I bought the insert at autoanything.com for about $37. I believe the Patriot, Compass, and Caliber all use the same one.

The recharge kit is actually worth the investment. $10 as I recall.

I recall a thread with a number of people suggesting the K&N would be harmful (letting in dust)- Never fear Jimmy, I am hear to witness No problem. I drive 50,000+ miles per year. I have put 200,000+ miles each on a Ford Ranger, Dodge Dakota and presently 135,000 on Chevy Colorado all using drop-in K&N filters. No problems at all. None of the vehicles burned any oil at all. I have Jiffy lube service change oil between 3,000-5,000 miles. I always put the filters in when truck is new so no mileage increase was noted. Try this, try to breath through a paper filter from house A/C. Then try to breath through gauze. Actually, don't try it the example is enough. Also, paper's open cells close when humidity is pulled through it. No question you did the right thing. And yes, I drove a lot over the last ten years.

Hey BN,

Yea, I read that.

I had also found a great test of various filters and the K&N did allow more particulate matter in, but it only makes sense since it has bigger inlet holes.


But I guess the bottom line is that although it is more compared to other filters, it is still not really enough to do damage to e 'well maintained' vehicle.

I hope... :)

Thanks
Jim

There should be some filter oil that came with it if not you might want to get your hands on some it helps trap the dirt but I do know that they filter real well and have been proven to work very well. You also will see more air+gas because the mass air flow sensor reads how much air is entering the engine and thus the computer supplies the appropriate amount of gas so... more air=more gas most factory intake systems and filters are really restrictive I know in my old car the intake was piped into the fenderwell :BLAM: anyways its late and I hope this makes sense!

I'm going to have to get myself one of these and try it out. Of course that means I'm going to have to figure out how to replace the filter... (I'm a computer geek with zero mechanical skills. I know...it's sad... I still read the instructions on the gas pump everytime I fill up to make sure I dont miss a step and light the place on fire.)

Don't worry. It's easier than working tupperware.

:)

Sure...that's what they all say until the burning and the screaming and the fires start...

Have you noticed any mileage improvements yet?

Have you noticed any mileage improvements yet?

Yes and no.
My mileage is up slightly the last couple of tanks, but its fall here and I have not had the AC on, so I can't directly attribute it to the K&N. PLus it was less than 1 mpg.

If you read reviews online, most folks don't notice much of a mileage improvement, with some who do giving such outrageous numbers its hard to believe. Also K&N on their site specifiaclally says 'We do not guarantee better mileage" or something similar. My mileage did not drop tho.

What it does give is a big boost in punch and acceleration, and if not careful that could turn into worse mileage from the fun factor.

Jim

Anyone say if the "cold air intake" from dodge caliber r/t fit, in patriot? its the same engine no?

Please use the search function. This has been discussed in depth here before.

This thread is about the K&N Air filter.

Thank You

My old mustang had that as well. It's to bring the cooler, more dense air into the engine.

Anyway, how much does the K&N filter cost?

It is suppose to last a gazillion miles.

I'm gonna change mine at a half a gazillion just to be safe.

I read on a web page a long long time ago about Turbo Charges and Superchargers... Any way point is that a Turbo Charges gets the vehicle more gas, etc.etc. fast car... A SUPERCHARGER gets the car more AIR...
So this K&N is basically allowing the car to intake more AIR... The one thing I'm not sure on is the gas?
However I will say I put in a Greddy "COLD Air Intake" (not just filter) in a 91" LS Integra and man did it give it a good punch! That car sounded so much beefer after that too...

When you rev the engine is there a throaty deeper sound coming out of it now w/that K&N?

I will be replacing mine eventually but when I find a Cold Air Intake System along w/exhaust... Normally you dont feel a dramatic change until you've up'd the engine 15+hp but that's what I've only been told...

Na, not really.


Still sounds like a big sewing machine.

I thought it was more of a "pissed off vacuum"?

At least the CVT and I have something in common... We both whine when we have to do something. ;)

Negative,

An engine works by burning fuel.
An engine can only burn enough fuel that it has air to combust with.

Both a Turbocharger and Supercharger force more air into you engine allowing more fuel to be combusted and therefore more power.
They are both essentially "fans" that blow compressed air in.
A Turbo is driven by exhaust gas, and a Supercharger is driven by a belt off the engine.

The K&N filter (Filtercharger) lets more air into your engine which makes for a more complete burn (more air means less unburnt fuel) giving small raise in power and fuel economy. The ECU may make small adjustments accordingly, but will essentially do nothing to the fuel.

Nice, maybe I miss-understood it? I'm just a PC Geek myself and act like I know some thing about auto's! ha!

I've heard that the K&N should not be used on modern engines with Mass Airflow Sensors, as the oil droplets from the K&N will cause them to operate incorrectly - especially over time and the oil builds up on the sensors. The other brands out there that are Dry Type filters should be used. (I'm open to corrections on this theory)

I've had a K&N in my Dodge Caravan for 9 years now, doesn't seem to be affecting it in any way... (just wish someone would buy it so I can pay for the patriot!)

I think that's bogus,
if the droplets come off the filter which is material and designed to hold the oil then they will most certainly come off the wire element of the airflow meter and into the engine and be vapourised. (we're talking very very fine droplets if anything)

This only happens when people do not know how to recharge the filter correctly, meaning re-oil it after you cleaned it. Some people think you have to submerge it in the charger oil...which in return causes you to buy a new MAFS in return.

Just got my KN today..already installed. Will know more this week/end. According to the 'butt-dyno' the car feels a lil more 'peppier' off the line for sure...as mentioned by other folks before...

you got a part number ollie?

yeah - sure: 33-2362


Here is where I bought mine from...took about a week to get to me:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ih=003&sspagename=STRK%3AMEWN%3AIT&viewitem=&item=130162649815&rd=1

there is a cold air intake and turbo coming out for this engine size soon if not already in some places.

does adding the intake void warranty?

Not until it sucks a big gulp of water into your engine.

From my experience a cold air intake only makes a small difference (1% or less) on high performance cars, and they are then more vulnerable to sucking in water from puddles or rain. Not worth the risk in my book.

Same for adding a turbo kit straight on to a non turbo engine.
You will get a huge performance increase to start with, and then things will start to break, and you will be forever in a cycle of upgrading to bigger better bits, and then something else failing.

The advice is if you want a faster car, buy a faster car, don't try and build one. It'll be like pushing **** up hill with a stick.

does adding the intake void warranty?


No - not unless the failure or the part is caused by the modification.

Magnussen Moss Act explains it all.

My cousin asked if I was going to put one in. I really never heard of them before researching it on here. I am curious to see what improvements they do

Have had it in for a week now and my engine loves it! It breathes easier and I have more of a boost especially in 2nd gear. Need all we can get here in Colo.

"boost"

you got a turbo on it already

:D

did anyone ever get a final MPG difference??

FYI - JC WHITNEY - LINK ("http://http://www.jcwhitney.com)
still has the filter for $41.99. It comes with the filtercharger kit.
You can purchase the HT Silicone Coating in black while you are ordering for $9.99 that way you can black out you muffler.
Use promo code SENDNOW for free shipping if you spend more then $50 :pepper:

no difference in MPG for me. I increased about 1MPG, but i credit that to having a fresh air filter and not necessarily the fact that it's a K&N.

I installed mine shortly after i got it (at about 100 miles) I aveage over 26 MPG (closer to 27)

I am getting 26 in town, and the worst i have gotten is 24 -- once testing what it would do, 106 MPH before i got into some hills, and once when i left my keys inside with the engine running and it took me 2 hours to get my spare and open the door

$32 on sale right now (http://www.performancecenter.com/product/partnumber/717)

ok, got it today and put it in, best 0-60 time was 11.25 seconds, 1/4 second better then without it... in the most optimum conditions... its much smoother, and feels like speeding up takes less effort (no more intense screaming!) overall I am very satisfied with the filter, and would defiantly recommend it... for $35 how can you go wrong? Just wished I'd done it earlier.

Installed mine last weekend. Didn't notice any difference. I have always bought the full intake kit but this time decided to just get the filter.

I have (2) 2007 Patriots a limited CVT2 with factory Air filter and Castrol Gtx, and my sport E model with CVT2 with K&N replacement filter and Castrol Syntec Oil. Gas mileage is about the same on both 23-26 around town 28-33 on the road depending on the road conditions. however the performance increase on the sport was extremely noticeable. As one of the other members mentioned the CVT is different and once you learn to drive it acceleration is not that bad especially with the gas mileage. Does it mke a difference, I think so but you need to make up your own mind.

Ditto.

I can't get my airbox back together. The filter fits fine, battery thing removed, buyt I can't get the bottom of the box to close. Help.

Never mind, I asked the mech down the street to get it. He fought with it too, but it's together after much cursing by two adult men in 93F heat.
