Pagka kuha sa box lagay na kagad. Yup madumi na bago ko nililinis nag babase ako dun sa may dirty side (pointing down) ng filter pag may mga malalaki ng particles at parang dust na kumpol kumpol. Na check ko din yung top part (facing clean side ng filter which is pointing up) wala naman oil pero may konting fine dust siya.

kay sir niky, may onting oil inside the casing,
pero sayo wala naman, getting different results here.
thank you din for sharing sir.

Thinking of getting a drop-in K&n air filter for my car.

but the "maf contamination" issues i always read bothers me,
mostly kasi puro "sabi nila" ang statement, even in international forums.

Ang gusto ko sana malaman ngayon, is anyone in the tsikot community
had engine problems after installing oiled filters, and proven that the cause of the problem
is that the maf sensor of their car was contaminated by the oil from the filter?

first hand experience would be really appreciated.

and those who are running their k&n filter for many years,
especially those who are using them 5years and above continuously,
kamusta naman engines nyo?

I have a 19 year old Lancer which I have kept for sentimental reasons. I installed a K&N filter on this Lancer a month after I bought it. It is a cone filter and is not one of the drop-in filters. It currently is still using the same K&N air filter up to today with no problems from the engine. I have only recharged this air filter four times in its lifetime and I do so every 20,000 kms as advised to me. (As advertised, these filters are supposed to be good for 50,000 miles before cleaning is required but that's for countries with less pollution than ours I guess). I remember being told back in the day that K&N filters work even better when they are dirty as the dirt acts as a filter for the filter. This car is running well and purring like a kitty.

I think the problem with oil getting into the MAF sensor is when you over oil your filter. I don't think the filter is supposed to be reddish in colour all the time but I usually hear of people cleaning their K&N filters as soon as it gets a little dirty.

For me, I go for the free-flow cone types to improve top-end (high RPM) breathing. This worked well in some of my cars (especially when i coupled it with a good set of headers) and had no effect on others. Now i just buy the K&N drop-in filter since it's cheaper than replacing my air filter every XXXX kms.

sayo naman sir, kamusta condition inside the casing?

im very particular dun sa loob ng casing, as much as possible, hindi sana nagkakalat.

Oks naman (clean with no residue at 25,000kms). I agree with Niky, hinay-hinay lang sa langis.

mga Sir,

question lang po, gusto ko po kasi nito pero ang hanap ko po is ung makakatipid ako sa gas.

pagkapoba nilagyanko ng ganito ung 1.3 na vios, bukod sa HP gain, titipid po ba sa gas?

currently 14.5KPL po ako, kung magiging 16~18KPL man lang ako kukuha na po ako nito. heheh

I wonder, would there be some real world benefit of slapping on an open type K&N short ram style on a 2.0L VVTi automatic Innova?

Very minimal. I have the K&N drop in on the same car.

You clean yours every 25000kms? Hehe ako dati kada 10k lang kasi nga masyadong marumi hangin sa atin. :bwahaha: Also because I have experienced a drop in my fuel economy and it went back to normal after I cleaned the filter. Now though, after 13k kms, my FC is still the same, kaya di ko pa nililinis ulit. As for the MAF issues, no problems at all after around 25k++ kms. and yes, just don't over oil the filter.

Edit:
Also do note that you're supposed to put oil on the "dirty" side of the filter ONLY. Yung inner part or yung papunta sa MAF/intake manifold ay di dapat lagyan ng oil.

For me, it's not oil residue. The residue is a fine film of oily dust. But that's after going a hell of a lot of kilometers (60k plus). I guess I should have recharged earlier.

Consensus is... if you clean properly and don't over-oil your K&N, you should be fine.

sir ano ba indication na over-oiled ung filter?

Sir Chicks, minimal ang improvement sa increase of FC, pero matindi ang dinagdag sa HP gain ng makina. so bang for the buck talaga pala siya Sir.
