Samarth, can you please explain the difference between an Airbox and AirFilter (am new to learning the technicalities).
Also if I get the K&N air Filters fitted...do i have to get my airbox out...which as per your above post will mean that dirt will get sucked into my combustion chamber making the piston kaput?

Wow thats really fantastic news for the pulsar owners.

Any details about the cost?? & availability???

The BA2201 is supposed to be a direct fit

great news....
Its good to see international players entering mod scene of our country and helping out pimping our lower capacity bikes too...
This gives more reliable way of hotrodding our bikes..:-)

as the picture depicts..its a stock replacement and doesn't require re-jetting or any sort of modification to ur air filter box! just remove that sponge bob and put in the cotton bob and ur done! performance increase a bit,induction noise is better and mileage improves and and higher cleaning interval's

its a stock replacement air filter, means no changes required to airbox.

BUT

in carb'd bikes you still need to do re-jetting.

i dont think so i had pipercross in my bike and still have and it doesn't require re-jetting air-fuel mixture is perfect no jerks no topspeed loss infact acceleration is smoother and better always..
i am sorry to say my friend but ur wrong and as k&n themselves said..no fuel management is to be disturbed! stock air filter MEANS running on stock/factory setting!!!

and obviously if they launched this specially for bajaj pulsar..they do know that bajaj doesn't have Fuel injected bikes!

well, any free flow air filter will increase the air intake of engine, so you bike will run lean, it may not give problems directly, but -

• it will make the engine run hotter, and may damage the engine in long run.
• if you fit a free flow filter and don't increase the fuel flow, then you are not utilizing the filter to its true potential, then you are just using it for sound benifit.

specially launched for bajaj pulsars does not mean you don't have to re-jet, it means no modifications are required to fit the filter, its a stock replacement filter which will go in the slot of stock filter. but, if do not increase the fuel flow, then you are not utilizing it for the purpose it was made for.

and if K&N guys say that re-jetting is not required, and if that is true, it means it is not a free flow filter and it will not increase the performance of your bike.

Good for you! But just check the spark plug color.

He may be running rich right from the beginning.

One look at the spark plug tip will tell the truth. then milk's milk and water's water will become....

Of course Abhee. You can say that your "Air Filter" gets fit into the "Airbox". Airbox is located often below the seat of the rider. In Pulsar you can access it by opening the side panel's key lock.

Every car and bike has a Airbox which protects the air filter from "larger impurities" like sand and rain water. Of course, the Airfilter does the micro filtering of dust, smoke, etc.

This is a air box from Apache RTR Fi which feeds fresh clean air to the carburettor:



Your piston goes kaput in 1-2 years, if you remove the airbox and fix the filter like many bikers have done before. This is dangerous:



Putting the filter without Airbox puts a lot of dirt and sand on it, which the airbox would have avoided.

Earlier we had no choice, as the suitable performance air filters by K&N came in conical shape... But now, we can fit it into our Airbox, so this rectangular K&N Filter is good news!

Conclusion: Just get the K&N BA2201 filter into your Pulsar's stock Airbox, no problems should happen. Don't wash it, don't clean it using compressed air at service station, just oil it regularly and you're done.

@ princesirohi and Mohit: Guys, I perceive that at different rpm's, different amount of air is sucked in the carb, depending on throttle. So, the upper limit of the air passage matters in any air filter.
Even when I had K&N, it didn't howl and perform right from 2000 rpm. Only when it was pushed, it sucked in more air on giving throttle, where a stock filter would be under stress.

So, it is possible that it might not require rejetting. This page mentions that a stock bike need not be rejetted:

i have perfect air-fuel mixture! i got it done by at bajaj service center using the emission level machine [which makes ur bike's afm absolutely perfect!] my spark plug tips are regularly cleaned at service intervals and they are not so BAD
infact i have one in my car as well [stock k&n air filter] it does say it increases performance but its just breathes better,induction noise is better and different and returned me a better kmpl numbers!
i think that's the same case with the bike as well! if u need performance from k&n air filter get ur self a conical one!

this one just increases cleaning intervals and sounds better

brother, just IF POSSIBLE, check your stock air filter(and air box) with any pulsar's stock air filter. if they are same, you can replace it. any pulsar-ba-2201 is same for all pulsars(150,180,220). but dont hurry, its not available in hyderabad now. i have enquired. it would come in one or two months.

has anyone used this on the 2005 pulsars . i am guessing the air filter box is the same and dint differ much on the later models except that the filter box location was changed to the other side in later models( in 2005 and before models its on the kick lever side)

Now even i am confused about the increased amount of air going to the carb if at all the filter increases the air flow then we have to re-jet the carb in case it does not then what is the real advantage of getting this filter .

if anyone has already started using this filter please comment on the difference noticed.

i am reallly interested in this new filter! i was in love with the sound coming out from the kn powered bikes. but never tried it because dont like to destroy my bikes factory settings..but now it is seams like it is easily usable without any modifications. but i am also confused about the a/f mixture amount. really want atleast that sound.performance not considered. but will be happy if performance increase as bonus.

found the the Installation instructions for the stock filter from the manual itself and it clearly mentioned that u dont need to change AFM because we should trust k&n! :P

PS:i got the price from sniper automobiles in dahisar its 2690/- and it will take a week since he starts selling and distributing it all over mumbai because its being tested as of know!
that's a heavy amount for "Stock replacement"
