K&N air filters?

[ramibel]

Side note dun sa discussion on gas saving devices. Ano masasabi nyo sa aftermarket washable air filters like K&N? Not necessarily yung cone filters. Yung washable replacements for the stock air filters. Was thinking of getting one, pero sobrang mahal. Kahit pa di mo na papalitan, probably for years, is it worth the cost? Also considering na it supposedly adds a little horsepower (2-3hp yata), though di mo siguro mararamdaman yun. Any comments?

[niky]

Not worth it siguro. Yung cone-type, di mo masyado maramdaman yung difference kung walang ibang mods, and you're getting the OEM-type replacement because you want it to appear stock, diba?

imho,
konting diff lang. pero better than stock.
i use simota cone type

Considering that replacement air filters for my rig cost less than Php 200.00, I'd rather have a brand-new filter at every oil change than spend for cleaning a K&N.

The engine breathes a bit easier but the effect isn't really worth all that.

Supposing one costs about 4000 bucks without the cleaning kit and is stated to last you 10 years. How much are you going to spend on air cleaners in 10 years?

my air filter is 550 pero oil chan ge..i change oil every 6 months.
i already got the savings of not changing filter every change oil.i dont know...but in the case of my ride (patrol safari and galant vr v6), the rise of the rpm needle is much faster...maybe different for other cars.

saken lang IMHO, I find it most practical to change the air cleaner into a cone-type filter..I'm using only Simota on my 7g and yet the performance of it is quite significant and manifested so to speak. I've been using this for almost 4 years narin,..still the filter has no signs of wear and tear,..(religious kasi ako maglinis ng filter),..rather than buying an OEM..gastos lang.. ..opnion lang po mga bros,..ty!

[GlennSter]

pano mo nililinis ang simota?

as far as i know...pag nilagyan mo siya ng oil like the knn ay mapupunta ang oil sa maf..which is delikado.

iba kasi ang components ng knn at simota...

I read an artilcle before which ran some tests for aftermarket air filters, it turns out they let in more dirt into the engine than an oem filter (in the test the oem was ac-delco i think), test results indicated that oem filters were still the best and the aftermarket filters let in more dirt, probably also more air, thats why you get a little 1-3 hp gain.

I forgot the link to the article, but I would suggest, stay stock.

[GlennSter]

well..i follow the 5k kms change everything naman...so no problem. i dont think the extra dirt could have affected my cars.

kahit naman oem filter, may dirt paring pumapasok.

[chris_d]

From what I read it would be a trade-off, either have more airflow/dust or less airflow/dust.

from my experience...it's not =)

used in my diesel ride na MAS MADUMI sa gas engines...not a problem.

The most noticeable change in aftermarket filters is the engine sound. Also, K&N's sucking of air is better than Simota. I've tried both and I can really observe the difference. K&N responds better the moment I blip the gas pedal.

Your engine breathes better with aftermarket filters. Yeah, it could be true that more dirt enters the manifold, but even with stock filters, there's always a way for all those particles to penetrate. You will just have to change oil a little bit more often.

[niky]

You could try what we used to do... naked velocity stacks on twin carbs... now that's dirty air. Of course, we put mesh material on top to keep pebbles out, and we had to change the oil a bit more often...

The extra dust and particles that the K&N lets in are minimal, and normally inconsequential, unless you have a sensitive MAF.

Aftermarket free flowing filters can theoretically let more dirt in. Not just because the filter media is more free flowing but also because using open-type filters disables the anti-dust systems of OEM intakes. Mitsubishi uses a dust pan on the Pajero, Nissan uses a pre-filter on the Patrol, Toyota makes use of the cyclone effect on the Land Cruiser. Some cars also have these built-in systems.
