erm, u seen the jet plane gone thru volcanic ash before? lol those dust melt and become glass. then jam up the jet engine. Hahaha.

They damage combustion chamber before they get combusted. Combustion cycle is 4 stroke. Stroke 1 down draws air and fuel into the combustion chamber, stroke 2 up compress the air fuel, stroke 3 down combustion of air and fuel, stroke 4 up exhaust.

Stroke 1 and 2 is pre-combustion and that is when the damage is done. If you suck in a small grain of sand, even the combustion stage is not enough to turn it to ash.

aiks... so in other words a forumner pointed out.. its a trade off between better performance and engine lifespan.

i also agree,

nothing beat rm20 paper filter,(rm18 after neg).

use n throw no need reoil.

Depends on composition of your dust...

Added on July 18, 2011, 11:30 am@dantck: Yup, very true...juz try yr best 2get good quality paper element filter eg Ori?

ps. Also dun 4get that better airflow may result in weaker AF mix & ECU may readjust 4richer fuel injection. Result? Slightly more power BUT higher FC!!

Again...YOUR choice...

steel mesh i used before, very bad filteration, i tested pouring some sand, can see alot of small ones goes through..

simota epoxy resin is kinda good as because its cheaper and better filteration then steel mesh, at least..

k&n is expensive because of the brand i guess

means the k&n pores bigger thn simota?

i dont mean k&n has bad filteration, i mean steel mesh filter in general

i think both are alright..depends on how much you are willing to spend, thats all.

for me simota is good enough for the price, k&n is rm100 more...

K&N is good if re-oil it properly, the oil element will stop the dust from flowing through the filter and don not over oil it, over oil will result to faulty sensors. Also clean with cleaner before re-oil.

not sure about the newer k&n but the old ones is definitely better than equally older model of simota steel mesh.
i'd been using k&n drop in for the fast few years, washing part is easy, diy and let it dry under the sun,
used to buy the re-oiling kit from speedworks, and i use em twice. too much oil will sometimes get in the way of the af mixture / sensor.
back then, when i check under the dim light, the holes of simota filter is much bigger than k&n(both are older model about 2 years back).

you can only choose either performance or engine lifespan ; but we can always have the option of getting
get a lil'e more power without compromising the engine lifespan.

btw, beside the other brand above, maddriver's air filter in garage sales is worth looking at.

SO any simota user here?
For some user just brought Simota/K&N can share abit here?
How's the performance?

Haven't tried Simota yet as I have few friends from J.. Club using Open Pod Simota Air Filter and the sound can be nicer than K&N. Maybe it's so called hole or filteration is not as good as K&N.

Have tried K&N but the worst part is taking out for cleaning and reoiling but Sometimes u will just get lazy when you want to do so and reoiling. Without making it right, you might affect your 02 Sensor. K&N drop in Filter might be abit over priced compare to other brands out there maybe because of its branding.

Thread revive to discuss. Any current sifus have anything to add.

Too all my sifus here respect 🙇🏻

I’ve tried and had both...

Simota cleaning filter was thinner, made more noise and filtration not so good. Cuz the filter was still blue clean after 20k. But low end rpm had slightly more umph “power”

K&N pocket pain and pain in the ass too reoil.
Noise is definitely more garang and top end better power then simota. K&N actually filtered better and is the better all round product.

But I’ve seen some sifus with simota air ram kit
And car flying....... 🤩 🤪 POWEREEERRRRRRR.

Yes noise preference is very subjective, the simota is
Definitely louder in terms of Noise DB generated.
But the k&n top end cry is much more garang, I like.

Drop in got sound ke? I thought open pod

I have used K&N filter and cleaning and oiling set. My advice is using back the stock air filter simply because the few psychological added hp doesn't not justify the cost (filter, cleaning and oiling kit). Furthermore, for automobile industry, there is one single golden rule "stock is the best" unless, yes unless there is a "major" modification. If not, forget about adding fuel card way of thinking, in order to save fuel or add few hps.

I used K&N very long time back on my old Mitsubishi, and now I just Simota/Works on all my cars (Toyota, Suzuki, & Nissan). Honestly no issues whatsoever, and you should not expect too much added power for just using such drop-in filters anyway. So in general I think the Simota is the best value for money. Anyway the material and design also basically copies K&N.

If you really want a good filter actually its not K&N also but APEXi dry cloth type filter but nowadays this product not available anymore. K&N/Simota give about similar filtration capability (plus/minus ya) but the main weakness is the oil which can affect AFS. The APEXi though is not using oil so it's cleaner like original filter yet it flows more air, believe it or not! Very long time ago there was a comparison test done on a GTR R32 between all these after market filter types and the winner was the APEXi as it gave the most power gain yet also provides equally clean filtration like std filter! K&N came 2nd with similar power gain yet got that oil trace getting sucked into, so not as clean. Then 3rd came the HKS foam filter which was very poor filtration and actually not as much gain as the first 2 also. Last was the Blitz metal mesh filter which gave about similar gain to HKS but practically did not filter anything hence very dirty! So for me I avoid any foam and metal mesh filters, no matter what brands!

I used to mod using performance air filter and open pod system.

I wouldnt recommend aftermarket performance air filter...the gain in power is close to nothing but the filtration is wayyy way worse than stock air filter

The open pod gives you nice intake sound tho haha
