Can you guys explain in some more detail?

Now, I would tend to believe your personal experiences than listen to some outsider. Both gurkha and steeroid. Btw, khader bhai I remember you told me ages back about a air filter company. Cant recollect the name. What are the other alternatives available for us? And RT, which company sells foam based filters in India to withstand track,drag and daily abuse?

I haven't gone thru the follow up articles that were posted, but why isn't anyone talking about a basic oversight that one other person mentioned as well - the tests were done on a (truck?) diesel engine. Do filters also effect petrol engines as poorly as diesels?

@Mclaren - is the filter efficiency for the stock on your baleno mentioned in your spec book from Maruti? Could you check?

mclaren 1885,

Don't know if you will like this idea, if you can manage space inside your engine bay, why not go for a bigger air box and a air filter than stock, you get more surface area for filtration and if you can put a fresh air induction, you will get some appreciable gain at dyno.

Not directly from the company, but I'm sure you know where you can pick up Uni or pipercross filters.

In our super dusty conditions, I'd go with foam filters to get that little bit of extra oomph without sacrificing on filtering what shouldn't be going through.

If a thin adhesive strip is stuck on after the filter, can the dust stuck to it after a day of use with K&N and with stock be a good indication of how much dust is the filter giving to the engine?

Not sure about Pipercross, but UNI's are not available in bigger size. Or atleast RC doesn't have them. Last I saw keshav was using them on his carbed esteem and they were bike filters.

I would love it. Lets see will take up this issue with keshav and see if we can come up with some solution.

You get them. If not in Bangalore, then simply order it online and get it shipped. That's what I did. It's foam, so shipping is cheap.

Also, they sell sheets of it that can be cut to any size/shape.

Someone at the MB forum suggested using Marvel Mystery oil dipped foam glued inside the air box path and checking it after a month.

But, I guess Uni didn't get such a good review either from the report put up by gurkha.

Tell you what, if I can't have TRD or HRC or HKS, then it would be Uni over K&N.

ScarySkulls · 5th June 2007, 22:40

Foam! It's a no brainer. NEVER trusted using K&N in any of mine or friend's bikes.
All show dusty inlets with K&N's. With the UNI's they are as clean as the stock OEM filters.
I have never bothered with the K&N concept of filtering....What was it? The more dirt that gets into it, the better it filters. Right?

So, do you regard that as a good point or a bad one?
