Washable K & N Air Filter

[Wh1stl3r2]

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

That's the one I'm afraid of bro. Given my clumsiness I'd probably over oil it.

How much ba ang maf sensor pag nasira ng dahil sa oil?

It has to be lightly oiled only as it will evenly seep around the element soon enough. You'll see with the pre-oiled filters that it's not really heavily oiled.

Depends on the car. A brand new MAF for our Altis cost around 6K i think.

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

Bro, the MAF sensor issue I'm not really 100% sold on, as it is hard to prove unless maybe we put it under a microscope. Can't swab it as it will damage the sensor. It most likely will not happen on correctly re-oiled filters. But the info on the link oj88 posted clearly shows K&N filters less particles. That info is also shown in the link I posted to the TDI Forum site. That increase in particles will show up most likely as increased silicates in used oil analysis. I don't think it will cause engine failure naman. Just accelerated wear probably. By how much I don't really know. For all we know it might not be appreciable through the natural lifespan of the engine. For me I guess if I will be keeping the car for hundreds of thousands of Km I wouldn't use it. But if I plan to sell the car while it is relatively young Km-wise, it is a good cost saving option.

Around 4-10k maf sensor depende sa make at model.

Di naman nasisira MAF Sensor unless nababasa yung filter or maluwag yung electrical connector. Incase wala sa specs yung pid ng MAF Sensor, buy ka ng Electrical Contact Cleaner (No Residue) sa hardware. Make sure na cold yung sensor before attempting to clean it. Timbangin mo muna yung filter bago mo linisin. If K&N filter mo check mo sa website nila yung weight at volume ng oil.


Wag ka masyado mag alala. Aandar naman yan kahit disconnected MAF Sensor naka ilaw nga lang ang check engine. Naka disable "Air Metering Mode" pag di na detect ng pcm ang MAF sensor. Disconnect mo lang yung battery for few minutes para mawala yung check engine light.

MOON LANDING SCIENCE naman yan.




May nabibili naman na Filter Wrap to add more protection.





Used Oil type Air Filter for Stock Intake of Ford Expedition, F150 at E150.

How so? Empirical data was provided in the tests.

And why resort to memes in a grownup discussion? Are you a child?

may nabasa rin ako last time sa mga koleksyon ko ng mga motoring magazines regarding air filtration. the best pa rin ang oem. sabi pa nga na mas maigi pa na hayaan lang yung filter hanggang sa kaniyang replacement interval...kasi the dust itself na nagaadhere sa filter will also contribute as filtering media in the long run. so habang dumarami ang dumi na natatrap ng filter e mas lalong lumilinis yung hangin na pumapasok sa makina.

nga pala, may ninote din na test procedures and protocols dun sa article na iyon....ayoko na kalkalin pa yung magasin ko na yun..nasa ilalim na ng hagdanan namin. maalikabok.


tsaka anong sense nung bibili ka pa ng filter wrap? bukod sa rason na added protection.

^ True, the tests were done in a controlled fashion and followed proper test procedures and standards.

And I also agree with the test results, which makes sense for any filter media that is coated with oil, that the K&N filter does provide more airflow at the BEGINNING but drastically tapers off and becomes more restrictive compared to a paper filter as dirt is exponentially accumulated. What this is telling us is that K&N filters may be ideal in motorsports where peak airflow is required only for the duration of the competition. However, I'd never recommend it for daily city use where the environmental air quality is considered extreme.

And those filter wraps were meant to be put on TEMPORARILY to repell water splashes or as an additional layer when driving in extremely dusty environments (think Dakar, rallycross, 4x4 off-roading without a snorkel, etc.) Again, it's probably NOT ideal for daily use.

Oh my! You mean that URL I posted was a direct link to my mind?

Are you reading what you're typing? Even more important, did you even read through the link I provided?

I gave you a link to a 3rd party study on the (in)effectiveness of K&N filters and instead of addressing and contesting each test parameters based on scientific facts, you've posted nothing but marketing materials and rhetorics.

Let me put it another way... people using paper filter media has reported no reliability or usability issues with their engines. But with K&N, you've got a lot of professional mechanics swearing that they're not as effective as the the manufacturer says they are. Of course that brings out the skepticism in everyone. If you're not skeptic as I am, well who then is the victim of the K&N propaganda here?

PS. I get it that you love posting memes... people who can't argue very well does it so, too.

I disagree, just wash it more often then it is still better imo in the long run.

This what Real actual data results looks like.

PCM Data log

[barako ba ma]

PCM Data log

your data and PIDS is just like any scan tool display. it does not show rate of filtration, how many microns allowed to pass through and how much resistance to air flow. stay within air filtration topic if you may.

[oj88]

PCM Data log

I'm sorry but it's like you're on a different planet.... you could might as well be measuring wind speed with a ruler. Your attachment doesn't say anything about the subject at hand, much less, prove your point.

But to humor you, let me just say that PCM data is subjective. It only takes measurements of what it needs to operate the engine as efficient as possible. For one, it does not measure particulate matter (which is an essential parameter for evaluating filter material). So basically, it can't distinguish what filter media is being used, or if a filter is present or absent altogether.

Do better.

So may we know the conclusion ? To use K&N or not ?
