but the filtering ability is horrible!
the holes are sooo big a needle can pass through it <check it out against the sun and u will see the whole sun.. and the material is not transparent!!>
its nearly as bad as running without a filter-- check out the intake manifold of any conical filter . wash the manifold in petrol or naptha ,let it settle down, remove the petrol. what remains is all dust .. u check out if u dont belive me!!!!
try this with stock filter -- u will never find dust in it !!

I think you need to know how a Cotton filter works when compared to a paper filter. Green Cotton filters upto 5 microns which is very very good.

Sorry but I am putting a spanner in this thread.

Years ago when I was much younger I remember helping my dad clean the oil bath oil mesh air filter of our amby and padmini and replenishing it with fresh 30 grade oil.

Going through this entire thread many are of the opinion that the filtration efficiency as far as particle size is concerned is relatively poor in after market air filters.
Few have mentioned the pin hole size orifices in the cotton mesh being the main culprit in allowing dust particle pass into the combustion chamber.
Now to my question.
The air filter in my dads amby and padmini had a wire mesh through which even a pencil could pass through. My dad only did regular maintenance on both the cars and both of them required an engine overhaul only after about 15 years and 2 lakh km.
Was the low tech OE oil bath air filters of yester years better than the ones we have now or was metallurgy and lubricating oils/filters better in the 70's.

Hey Casinova,go for Green cotton "Wind".Wind normally use for cars having BHP upto 100.Wind is Rs 3800/- only.

Someone threw away some of the other important components, IMHO!!

Down rate the engine specs for Indian conditions, horrendous pricing of most cars when compared to international prices. Supply of age old designs and outdated cars that are no longer in production in most parts of the world (M800, esteem etc). Pathetic build quality of the same vehicle when compared to internationally (prime example is swift). Lack of providing power windows on the same car across different variants. And the list goes on. Have you over looked all this?

Since you seem to crying your lungs out asking people to stop polluting the environment by modding cars just wanted to know if the same applies in all fields of life (fair enough). Or is it just that you suit your theories based on your priorities?

There is no harm in trying. But end result is it WILL still lead to more arguments. And am I willing to waste my time over such petty arguments? NO! But still will give it a try.

This is the filter I am running on my car. Yes, it MAKES A LOT OF DIFFERENCE. Why? Go to my gallery and check out the mods to my engine. I have had days when the filter was clogged and I had to swap to the stock filter and my car was getting choked. LITERALLY. So, yes filters do work. Link to the specs of the filter.

If you have any queries feel free to read this.
K&N Frequently Asked Questions (FAQ)

Many will argue saying these are for cars abroad and not meant for our conditions or cars. But having used them personally I would say they DO make a difference. Get onto a track or a drag strip, take of your air filter and run the car. See the difference.

If you need filtration tests you can check out this link.
K&N Product Testing

What is the theory behind which air filters work?
In a society where FE matters most, there is a chance that most manufacturers MIGHT be running a slightly leaner mixture (restrictive intakes) to get that extra yard out of a drop of fuel. So adding additional air can lead to striking the appropriate AFR which only betters the efficiency of the engine. This will not only leading to proper burning of the fuel but also increase the power and torque too (naturally). And increase in torque will only translate to better drivebility which in turn will increase FE. So yes, it is possible to achieve better FE & Power with an air filter. But the extent to which it helps is debatable. Some manufac's might run a more lean mixture compared to others, so certain cars might have profound changes to the addition of more air.

Do note that most manufacturers WILL not recommend any after market accessories. Look at Skoda dealers who infact even say that Pete's is dangerous & useless . Though its been proved otherwise after lots of testing and dyno proven figures. It goes to say that your warranty is actually VOID even if you get a stereo installed from outside the showroom. Or get a service done from a non-authorized center. Same applies to engine mods as well. Any modification you do, engine, electrical, brakes, tires do VOID your warranty with immediate EFFECT even if its for better safety, driveability etc.

Due to this lack luster attitude of most of our manufac's they will never come forward and support an accessory until the Government makes it MANDATORY. Isn't that why all these Euro Norms were brought upon? Because the Govt enforced them? And not because our esteem manufac's decided to provide them because of good will?

Talking about figures, I would say wait until that day we have dyno's that are available all across the country for public use. Some of these theories have been proved by some cars running in the rallies/tracks in India which do HAVE access to Dyno's. SO it is not all baseless and pointless. Or I am sure they aren't fools to run them either if hey didn't have any gains. And we are talking about some really professional and popular tuners here.
I don't think most have seen Anup's POV here. I see everyone talking about how the tyres are downsized to cut costs. Sometimes the stock headlight bulbs are lousy(mine were and I had them replaced).
How many manufacturers do you see advertising their tyres or their headlights in their advertisements?
If an air filter truly improves power and FE, surely a 5 K increase in the cost of the car would be nothing compared to the benefits of advertising a car with higher FE and power!
I don't think Anup wants to dicourage people from the mods. But he has his doubts and is justified in getting them cleared.

Product Reviews - Corvette Product Reviews and Opinions - Green Filter

Rgds,
turbosam says- THIS IS WHAT THE LINK SAYS!!!!
I've been testing Green Filters on two different cars since the fall of 2002. One of them is a 1995 ZR-1. Admittedly, at the power level of my engine (about 500hp) there is no performance advantage to the Green Filter over a new, stock paper filter because of the filter area. The stock paper filter used on '89-'96 Corvettes will provide enough air flow for about 600 hp. This is why, when I ran a dyno test comparing the engine with no filter assembly at all to a oiled-cotton filter in a stock filter housing with an open-element DRM air filter top, there was no difference in performance. That situation changes as the filters trap dirt. Because of the different way oil-cotton filters work, they are capable of higher air flow for a given level of contamination than is a paper filter. So, in this case, with a filter as large as the panel filter used on a ZR-1, there's no difference when the filters are new, but after some time in service, the paper filter's ability to flow air decreases quite rapidly whereas the oiled-cotton filter can trap the same level of contamination and not restrict.> then turbosam was forced to think that--
the cost of oiling the green filter <may be @ 250-500 rs i dont know but i think think > is more than the original stock paper filter element!!
plus the original purchase cost which is in multiples of the stock filter ..

AND AS THE ARTICLE SAYS K&N filter actually drops the power... <I've used K&N Filters for nearly 20 years in my Corvettes and other cars. About a year ago, I was running my '01 Camaro on K&N's chassis dyno, testing one of its Filtercharger replacement filters. I was surprised to find that filter responsible for a small performance loss compared to the stock, ACDelco paper filter element. This seemed unusual to me because: 1) the testing was on K&N's own dyno, 2) I ran the test more than once to confirm the results and 3) it was the first time in nearly 20 years I saw a performance loss after swapping a stock filter for a K&N.

It struck me that this particular Filtercharger might have been defective, so I asked the K&N folks for a second filter and some more chassis dyno time to retest it. Unfortunately, they were unwilling to fulfill my requests. At that point, speculating that K&N's reluctance towards more testing suggested a problem with the filter design for the particular vehicle I was using and not a single instance of a defective product; I returned the filter to K&N, thanked them for the dyno time and investigated other options in high-performance air filters. That led me to the Green Filter.> now turbosam asks all the readers,
what do u say about the whole story?

green vs k&n

have used both brands in several of my cars over the years and both brands provide far superior air flow compared to oe stuff and when properly maintained better filtration as well - the oiling of the gauze traps dirt but still allows airflow. a fully clogged oiled gauze filter flows better than a oe filter - thats why they r used in the baja 1000 and other desert/dirt events. a clogged oe filter will tear open and not offer any protection.

just fit a green storm to my honda civic b16. was running a k&n universal cone earlier - totally shocked with the results - the car was not slow by any standards with the k&n would rev real easy to 8700 rpm but now with the green, the low down torque is much higher and from 6000 t0 8700 the car is so much punchier , the rear actually squats on acceleration.
