Anyone have any experience with one of these? Pros/Cons? I'm thinking about getting one for my envoy. I had an Injen on my spec-v and loved it, but they dont make one for this car.
I can get it for $209 Shipped. Any better options? Will it be legal if i want to get it inspected in NC?

you might as well just save your money and take your air intake assembly/filter off.

2/21/2007 7:38:15 PM

teh waste get a k&n drop in.

although my 'cai' did improve throttle response on the celica.. lolz

2/21/2007 7:39:33 PM

a drop in isn't any different. might as well just pull out the filter, you'll get the same gains and the same filtering.

yeah i put stock one back in celica the filtering sucked on the wanna be k&n

2/21/2007 7:46:36 PM

one option: try mimmicking what the dodge dudes do with their cumminz - big fucking paper filter clamped into the factory intake hose. Altho i dont know about the design of the factory airbox/intake tubing/etc., I'm guessing any gains would be minimal.

If you insist on getting one, this would be my choice for aftermarket intakes:

(here again, the filtering media might be comparable to K&N)

I'm not really looking for gains, but better mpg. A link the the dyno sheet:
http://www.kandn.com/dynocharts/77-3036.pdf

Like I said it made a difference on my other car, I think it would make a difference on this car. Its not a "tornado" thing.

^More money, seems like its still uses an air box. got any pics of the inside?

2/21/2007 8:16:28 PM

decent gains, more than i expected.
probably search the volant website for more pics.
I'm a fan of a properly designed airbox and intake system. remember, the airbox might not be the limiting factor on the cold side of the engine. (and I admit, there may be some tuning differences that I could be overlooking regarding intake design - length diameter whatever) the volant does have a smoother bend than the K&N, and the material might conduct less heat than the K&N. who knows

2/21/2007 8:26:29 PM

^yea, but im not racing it, its a SUV... i just want a little something. Plus i know the K&N will prob give me a better sound.

2/21/2007 8:57:29 PM

hahaha

if K&Ns mottos matched their clients:

"Still giving false gains to ricers and truck bois for 25 years"

2/21/2007 9:00:14 PM

i wasnt really referring to racing through mentioning proper design, if im going to spend money, i want it to be worth it. and like you said, it IS an SUV - you'd probably get similar results by going to autozone and slapping on a cone filter (by the way, autozone does sell components to construct your own intake - that could be an option)

2/21/2007 9:03:03 PM

Any other comments? I'm gonna buy it this afternoon i think. I've been looking on an envoy message board, and they seem to like this one as well.

2/22/2007 12:19:20 PM

I've got an air raid on my truck. I notice a difference in mpg when the filter is clean.....after a few months it goes down until i clean it again

2/22/2007 12:31:44 PM

i cant tell a huge difference between the 2, both look good.

2/22/2007 1:17:19 PM

your cylinder walls will be so happy...

2/22/2007 1:18:49 PM

^speaks the truth. go find a paper element to slap on it

This is because the clean filter flows better, while the dirty one filters better. To simplify, engines are more expensive than fuel so DONT CLEAN IT SO MUCH. Once a year is as often as I would clean any reuseable filter for on-road vehicles.

2/22/2007 1:29:19 PM

I usually clean mine every 6-8 months. That's too much?

2/22/2007 1:39:57 PM

yes!

2/22/2007 1:57:48 PM

I always thought that the oil was the integral part in catching fine particulates, and the filter needed to be cleaned/oiled to keep it working properly. (too much oil is bad, i know).

so why wouldn't it be better to not clean it at all?

2/22/2007 2:02:47 PM

the filter is gauze. it has very large openings in it compared to paper media (which is why it flows so much more) and in order for it to filter much at all it needs to be oiled. it sort of makes the gauze sticky and traps dirt in it. the more dirt trapped in it the smaller the openings, and even more dirt gets trapped. which is the whole point of an air filter. eventually it will get so dirty that you need to clean it, but even K&N used to advertise that their filters worked better when dirty. and they are no different from any other reusable guage filter.

2/22/2007 2:11:15 PM

yeah, i looked, and k&n actually says it only needs to be cleaned once every 50,000, which would be like 2.5 years for me

now i know.



would oiling it a bit w/o cleaning help or hurt?

2/22/2007 2:15:56 PM

spray the oil on till it wicks throughout the media. dont overclean the thing, but for gods sake dont let the pleats get filled with shit. that's terrible

2/22/2007 2:19:45 PM

I know over oiling is a no-no, but re-oiling a bit after 20-30 thousand miles couldn't hurt could it?

2/22/2007 2:22:44 PM

you dont need to reoil

2/22/2007 2:31:00 PM

K&N arent made of gauze, green filters are though.


Theres no need to reoil except after a cleaning. Put it in and forget about it for a while.

2/22/2007 2:47:58 PM

They most certianly are made of cotton gauze. What did you think they were made of? Sunshine and puppy dogs? Hopes and dreams? Magic pixie dust?

2/22/2007 2:54:56 PM

i've had k&n filters on most of my trucks because i have to replace paper ones so often and i have never had any problems, the particles that get through are >10microns, slightly larger than bacteria, not large enough to cause damage or contaminate the oil, hell i have run my new truck over 100k with a k&n an 25k oil changes and it is still fine, i just clean the filter every few months, for $65 + a $20 recharge kit, it has taken the place of 7 $18 paper filters so far and $85<$126

2/22/2007 3:20:27 PM

it has 120k miles on it already, im only looking to get about another 30 or 40 out of it, so i think ill be good.

2/24/2007 2:54:23 AM

Did you ever put in the CAI and did it help any?

2/26/2007 10:11:04 AM

well im going to order it over spring break, i didnt want to get it over spring break and have it sitting outside my house for a week. but ill let ya know and post some pics when i get it.

2/26/2007 3:11:09 PM

So there seems to be a good amount of feeling that the K&N is overall detrimental to an engine if the power gains come at the cost of filtering...hmm. The Marauder has a K&N setup on it that was there when I bought it...57 Series FIPK, http://www.knfilters.com/search/product.aspx?Prod=57-2563
I almost wonder if I should go back to the factory airbox & filter, but I'd have to buy a new one since the original setup did not come with the car. Do y'all think that would be a wise purchase? Or am I worrying too much? The car only has 46K on it right now, but I intend to keep this one for a while and I don't want to discover that I have major damage to the engine down the road from ineffective filtering...

2/27/2007 10:55:38 PM

K&N is the bestselling filter out there so it cant be too bad. I wouldnt worry about it, but if you really are then just change out the filter to a Green or equivilent.

2/27/2007 11:36:40 PM

If you're worried, find an equivalent cone filter (of a different material type) and clamp that shit on.

[Edited on February 27, 2007 at 11:41 PM. Reason : dur]

2/27/2007 11:41:02 PM

^very good alternative. there are a few applications out there that use open element cylindrical type filters made conventionally.

^^haha, there's some great logic. everyone buys it, so it's gotta be okay.

^^^if you're planning on keeping the car for a while (40-50k miles or more) definitely get rid of it. i've seen a number of motors that look like the cylinder walls were sandblasted. obviously blow by was an issue.

do some googling, there are plenty of reports with hard evidence telling the effects of k&n.

the thing is, most people don't keep a car these days long enough for them to have to deal with the issues.

personally, i'll slap one on my vehicles. i rarely keep a vehicle very long, and if do i'm not worried about having to do any internal work. that doesn't change the facts of the damage running one can do.
