Ya guys,
please.
Is it worth it? Have saved up enough to get them for our palio.

I suggest we should look at other brands since K&N charges 5 times the price just for the sake of brandname. Our own team-bhpian PJSPEED sells performance filters of another brand for less than 1000 bucks.

I personally went and checked out those filters and they are no way inferior in quality to K&N.So, am planning to fit them in my cars after the chennai floods are done.

It doesn't make sense to force anybody to recommend for or against the K&N filters. The articles and a lot of test results are up, now you've got to read and decide. For every one person who doesn't believe in K&N's claims, there will be one person who's already experienced increased performance. It's not fair to either.

[nitrous]

I agree, ported. Apart from MHP, there IS a difference in BHP too. if not, there's no way K&N sells well,everywhere.

PS: I believe in the 'K&N" concept rather than the brand.

Here are the test results of EV500 filters

I think K & N has more to with MHP and sound change rather than a substancial increase in actual HP. My freind and I have a Swift and he got his Universal K & N installed in his car from Karol Bagh. He invited me to check his ride out and was all praise about the wonders k & n had done to his car, increased his mid end toque, etc.
So we wet to Delhi - Chandigarh highway on both our cars to have a 1/2 km drag race. I was able to beat him two times and he was able to beat me once. So that goes ahead to show, even though he was feeling that his car was rev happy due to the sound, but his gains were just more mental than actual. In the end it was down to our gear shifts that decided who won. So I again thank Mr.Kamath for highlighting K&N myth.

Like you said the gear shifts decided who won.... And probably the condition of the car, tires, driving confidence, etc also matter....

So you were driving your car and your freind on his with KnN filters. This time you drive his car and let him drive yours in a drag race. Though your freind might cheat on you and let you win. but you can figureout the diferrence.

Well, iam all in for KnN filters. It may or may not increase performance, FE or whtever but at the end it filters air and dont let dust getin, which is helps my engine live a longer and healthy life.

if im not mistaken K&N filters both the OER filter and the conical filter have bigger holes so they let more air and along with that more dust into the engine.the stock filters hence block more dust particles and hence are more effective if thats what your concerned about.

Thanks i didnt know that.

look at the brighter side. bigger hole mean more oxygen and these filters are suppose to filter dust equally or better than stock filters.
I hope iam right that KnN filters filters dust better than stock

The engine will be breatheing more oxygen than stocky filters.

[aseem]

No, according to the articles posted on this thread, K&N filter allow more air in, which also results in more dust particles. So on the contrary they might effect the engine life.

[fieroid]

k&n filters use cotton gaze which is a material that is known to filter better than the regular paper that comes in the OE filters. The best part about k&n is that they offer more air flow and also filter much better. However if dust is a concern for most of you, u could use foam wraps for the k&n conical filters which should give peace of mind for most of us.
I have used K&n in my bikes in the past and found that there was not a speck of dirt in the carb or the cylinder manifold or any other related parts! I also applied a tinge of grease on the carb inlet to see if any dust settled, but was still clean. Want more proof?

Hey man.... Thanks a ton for clarifying.... I was minutely disappointed after i got the K&N for my esteem about the filtraion aspects from what i read above but now i am satisfied.

But wont that reduce the airflow capability you gained on account of the K&N?

What was the situation with the stock filter...did you find any dirt with that?

My only argument here is that, if the question is of cost vs. gain, then I am sure the K&N loses out.

On the technical front, personally (I repeat, personally) I feel that a good, large-diameter (larger than stock) foam filter is more than enough to do the job (because thats what I have used all the time, even on high-rpm race 2-strokes). K&Ns are no good at all on the dirt track.

fieroid, as an aside, do our hosur friends use K&N? I think not, though I am not sure....

Here’s My reasoning as to why manufactures do not go in for K&N as an OEM Fitment

1) Maruti Says that you should just fill unleaded petrol in your vehicle, Don’t use power or speed or petrol with Additives? Where does this logic apply?
2) A Free Flow exhaust system with a header configuration of 4:2:1 is proven to be better that the 4:1. Why don’t cars come factory fitted with this?
3) Are not iridium spark Plugs better than the normal copper ones?

I have just quoted 3 examples; if manufacturers had the customer’s best interest at heart then we would have had cars that gave a far higher FE & better Pep.

We could go on arguing about the Pros & Cons of a K&N Filter.
Well If some one has a specific case where there has been a reported Damage caused by using a K& filter please do let us know. I have been using my Stock K&N for almost a year & I am extremely happy with the difference in the drive & FE.
