is the K&N drop-in air filter bad for your car?
im poor.
i been gettin little things here and there for my car over the past weeks since i bought it, but i have big items, like brakes/rotors, knock sensor, etc. that i NEED to start saving for. the idea of dropping two or three hundred on a cold air intake is out of the question right now.
i mentioned in a previous thread that i was thinking about gettin the drop-in K&N air filter for my stock intake and for the most part the response was positive. but there were a couple of people, i remember ILYAK in particular, who said that while the K&N drop-in would allow more air, it would also allow more dirt and dust into the MAF and TB. he said he opened his TB after a couple of months of use and it was dirtier than hed ever seen it.
here it is:
http://www.courtesyparts.com/Merchan...Code=33-2031-1
does it really allow that much more air? boost hp? i remember some kid saying 5 hp, which aint much, but it all helps.
does it let more dust/debris in than a fram air filter? supposedly it doesnt, but then again a website writeup will say anything to get you to buy the item.
there is an oiling process, i guess to keep it moist so it can catch stuff. how often am i going to have to oil it?
basically, is this 44 dollar item worth puttin in my car?

I would not pay 300 bucks for any CAI. Either stay stock or get a PR Clone off of ebay. I bought one off there, and didn't notice any power gains, just noise. I was using th K&N drop in filter and there again, noticed no gains. Our stock intake is fairly decent, so anything else would be very minimal and def not worth 300!!!

i mean i was just using that as a rough price idea. i havent even begun to investigate aftermarket intakes. i need brakes and KS and a lot of other sh*t before i start doin that.
back to the thread....
is there anything i can do to CHEAPLY modify my stock intake? im thinking like 50 bux or less.
ive read things like hacking it (drilling holes, removing the "scoop") and also ive seen these aftermarket "high flow" air filters for 30-50 bux.
anyone have experience with these things?

Then don't waste your money on crap like this. Stick to maintaining your car, not modifying it.
Maintenance before Mods
This question is answered on thier website and on the back of the box and in the instructions. I don't remember offhand, but it's xxxxxxx miles or when it's really, really dirty. Whichever comes first. Clean, re-oil, re-use.
Return the K&N and stick to maintaining your car. You want real performance, you're gonna have to pay for it---->FI

yes replace with K&N filter. Your supposed to change ur regular paper filter every 12k miles, i believe. The k&n are good for 1 million miles. You dont even have to clean them that often, maybe every 50k... but depending where you drive too. This alone will save you a good amount of money on having to have to buy crappy paper filters every 12k miles. You wont get any HP from a drop in panel filter.. or any intake to be honest. But if you want a nice growl out of the intake, id get a CAI. They sell them on ebay for 20-30 bucks shipped and they work great. Just make sure to also buy a quality cone filter, probably from K&N. You will need to drill a hole in your fender tho on the inside near the battery. Also check the for sale section someones always selling something for cheap. Just my opinion to you.

I have a K&N drop in air filter, purchased in May 2004. The filter has 18,000 miles on it and does not need to be cleaned yet. I used to only get about 22 or 23k out of an OEM filter, not 30k as is the recommended replacement interval.
The K&N filter should not be over cleaned. I read on BITOG that it should be cleaned about as frequently as you would toss out the paper filter.
So I will take another look at mine in about 5,000 miles and decide if I should clean it.
I have read that the potential exists that increased silica levels can be seen in oil, following use of a K&N filter.
I am going to send an oil sample to Blackstone Labs in a couple of months to check on this, as well as to determine how my synthetic oil is holding up.

given your situation your best thing to buy for HP will be a knock sensor. a bad KS will decrease HP by around 20. then after all other maintenance, save up for a CAI cause it seems like you do want one eventually. why buy an expensive drop in filter if you plan on replacing it later? CAI are like $40 on ebay, then put a K&N filter on one of those.

This again? 
Tell us why you want a modified intake so badly?
Power? =
Unless you get the belt-driven intake.
Sound? Just go on eGay and get a cone filter and MAF adapter. Easy to install and you can't take it out easily to put back the stock one.

no HP increase
Get rid of the Fram and get an OEM,
they're cheap, and they WILL save your MAF,
ALL paper filters will kill your MAF at an alarming speed compared to OEM oiled filter.
And conisdering the fact that you said you're poor at the beginning of the thread....
GET OEM.
and replace your KS and brakes ASAP, forget the K&N, you're just buying a name, and a ridiculously overpriced one at that.

paper filters allow more and larger particles through, which will toast your MAF a lot faster. They'll also grime up your TB and IACV faster, thats been proven time and time again. OEM is cheap, better quality, better peace of mind. That IS my .02 though. Should've put that down on the previous post:stfu:

OEM is paper...I just got my OEM...it definitely didn't look or feel anything like the K&N. What "OEM" are you refering to? Cause I walked into Nemith Nissan in Latham, NY and asked for a 99 Maxima Air Filter and that's what he gave me. I doubt they have different versions of the same damn filter.
I got rid of my K&N after 4500kmi because it was affecting my idle (dirty TB and MAF). Please don't tell me nothing about the K&N. All it is good for is increased air and louder tone. That's it. I'd rather have a proper idle and less air than a car revving ITSELF and a dirty as TB and MAF (and a dead MAF at that).
Boo for K&N.
Do what you want original poster...but be aware, very aware. Your over-priced K&N air filter might cause you hundreds of dollars in parts costs later on down the road.

Well...I think factory ones are better. My dad has never cleaned a MAF or a TB in his entire life on ANY of his cars and has always used the filter that came with the car...took it out occasionally, washed it, dried it with an air gun and put it back in.

Um, a K&N isnt a mod. its still a maintenence part. :stfu:
K&N is alot better than OEM, K&N sums it up just right by saying its like having a person breathe through a straw, thats what its like with a oem filter.
K&N allows the engine to breathe. it filters much better too, its the best filter on the market.
get it.

OEM filters have an oil coating, they're not 'just' paper, that's what I mean when comparing them to 'dry' paper filters. Even if you get a AE filter that you oil its not going to do the same job. Also the OEM's arent washable, they're a replacement item. Like I said though for 15-20$ I'd prefer the peace of mind and quality.

[QUOTE=f550maranello2;6039337]K&N maintenance part... i think thats an opinion. I think his advice was very good. It is better to fix your car then to try to mod it. Seeing that he has a bad ks a filter that cost that much money...waste of time. Why did you have to be so ***.holeish about it and tell him to join the honda civic forum? I think he knows what he is talking about.

Dude im right there with ya, but come on it will allow something ridiculous like less than 1% more air compared to a paper filter, + you will need to clean the k&n using a kit which costs money as well
here read the best air filter test i have seen on the web:
http://www.bobistheoilguy.com/airfilter/airtest1.htm
Its not worth it, paper filters better, its cheaper, and is within 1% difference of the performance of the K&N - also you are not going to keep the car long enough for the k&n (due to its high price and recharge kit price) to pay itself off!
why let more dirt into the engine, and pay more money doing it ???????????

please dont get rid of the cats - gains are minimal - maybe even non-existent and you will be harming me and my future kids and my future grand kids by allowing bad gases into the atmosphere...

You dont know that, we will not live to see this, and why add to the problem when you can be part of the solution ?
basically if there is anything i can do to save the environment i do it, i know its very little and there are huge businesses and factories that dump dirty chemicals into the atmosphere (i worked for one in the past) still, i like to think i am helping the environment, not killing it...
anyways thats off topic here
