Washable K & N Air Filter

[kimbon]

Can I use dish soap to clean only K&N air filter without the kit cleaning? TIA

Almost everything is disposable nowadays. Air filters of yesteryears were washable oil bath steel wool filled air filters then changed to dry paper element disposable folded accordion air filters. Now, back to washable air filters? Just like the pasador before the disposable sanitary napkins. Is technology going backwards?

are k and n air filters made of steel and or aluminum?

pwede din ata if you use a mild kind of soap pero you need to oil it again w/ the k&n filter oil so might as well go w/ the cleaning kit na lang din

Non detergent based yung pang linis ng K&N. Hugsan mo lang, wag mo sabonin. Mahirap alisin detergent sa filter. Bilhan mo ng filter wrap para may damit yung filter mo.

If you were to dress a filter with a pseudo filter around it and oil the K&N filter, consider the restriction it will give your air induction system. It would put this indicator on the red all the time

I only use joy dishwashing liquid. Pabulain yung joy sa timbang may tubig just enough para dun knn air filter then babad for 30 minutes to 1 hour then banlaw ng maigi.

Then patuyuin but wag na wag ibiliad sa araw. Then apply singer oil. Good to go ulit.

So far 4 years na and still looks and performs as brand new.

Not meaning to spark a debate. I'm just airing an opinion and I fully respect peoples' decision for using or not using K&N filters.

Apparently it seems, that K&N filters, by nature of them being reusable, do save you a bit of money that would otherwise be spent on throw-away paper filters. But is it really lowering TCO? Is it providing better filtration?

Honestly, I haven't used them. I have considered using K&N filters but decided against it. I view them as performance drop-in parts that may marginally increase airflow but at the expense (it seems) of filtration ability. In my head, they're more adept at motorsports where engine performance is paramount while engine reliability and longevity takes a back seat. But for any other types of driving, especially daily-driven vehicles, OEM filters, to me, appears to be the better choice.

I've posted the same concerns re: oiled filters several times on this board. It is also discussed at length in various forums. Not just K&N but most other aftermarket CAI as well. Another major concern aside from filtration ability is the possibility of loose oil being deposited onto your MAF sensor, eventually destroying it.

Not really trying to dissuade people from using it as well, I just hope people who use it are better informed of the potential risks.

Just a thought:
If you don't mind the intake noise, why not place the air intake next to the evaporator inside the car. 1. For cleaner air quality- the same air you would be breathing, 2. With the air conditioner on, the intake air temperature would be colder and more dense.

may napanood akong video sa youtube, umangat yun measurement nung equipment nila nung nilagyan ng extension yung intake sa labas ng auto. di ko nga lang alam kung ano yun tumaas ^_^

Most definitely. Backfires would also be much more fun. It'll sure help sear off those unwanted leg hairs on the Mrs.

with diesel engine equipped cars and since the advent of electronic gasoline fuel injection, i have never heard of engine backfire. if you have, let us know what vehicle and what engine. also, with electronic fuel injection, i haven't heard of dieseling or engine running on with the ignition shut off, if you have experienced one, please let us know.

it will probably result in a warmer passenger cabin. because the intake keeps sucking cool air from the cabin, warmer, outside air will come in.
it will probably be not an issue in places where where temp is cooler, but in the phils, it will probably be an issue.

That's only a myth. They are just using FEAR to scare you to keep buying overpriced paper filter. Did the "so called experts" showed you any Scientific evidence to prove their theory? May air filter din naman na washable na hindi oil type.

"If you don't control your mind someone else will"

2 ang maaring daanan ng air papasok sa engine, sa Air Filter at EVAP Canister Vent.

I'm using Washable Oil Type Air Filter for more than 15 years and I never experienced a single engine failure. Once lang ako nagkaroon ng konting problema noong first time kong linisin at magrecharge ng oil sa filter. It's either na di pa masyadong dry yung air filter nang nilagyan ko ng oil or baka sobrang dami ng oil na nailagay ko. I'm still using the stock MAF Sensor until now. A Cheap Generic Scantool will give you access to MAF Sensor PID.

MAF PID * hot idle no engine load
4.0-5.1g/s
0.52-0.67lb/min
0.6-0.9 DC Volts

Well, he's not a robot. I'm sure he's still capable of a little humor. Otherwise, that's probably going to be the one single bad advice coming from him.

There is truth to it naman. Given the same surface area, better flow will always come at the expense of filtration. Di naman masisira agad yung engine but definitely bigger particles will get past and cause more wear. Impossible to know by how many kms it will reduce engine life but to be conservative, the potential to do more harm than oem is there. While you may be able to have run the engine for X km without problems, it may run for X + 100TKms if on oem. That's not even accounting for oil on the maf sensor.

The only benefit I see that attracts most people to K&N is the promise of lower cost. Most oem filters flow more than enough air for the engine.

I purchase K&N drop-ins precisely because it's reusable and pays for itself in the long run.

As for MAF sensor issues, we've been using K&N since the 90s and so far i've only had one MAF sensor problem and this was with my 2007 Corolla at 120,000kms. I doubt it was due to oil contamination although we also regularly clean our MAF sensors. A more probable cause could be the poorly designed and mounted air intake tube and MAF sensor mount as we used a K&N cone filter for this unit.

Another thought is possibly some put too much oil when they "recharge" the filter?
