"Paper is used as filter element because it lets lesser particles through than cotton"
You are absolutely wrong, paper is used not because of its character to let lesser particles. For a filter paper, letting the particles are purely based on its pore size.
I believe it is widely used since it is cheap to afford and less effort to maintain.
The filtering of K&N is not just based on its pore size. Remember 1 thing, your paper filter will also let the particles which are less than the size of its pore.
I request you to read it again. I said that since you have claimed cotton is infact cotton.
Do you think they undergo engine rebuilds only because of the usage of performance Airfilters?
I believe those race filters are far different from this stock replacement filter that i use in my car.
Yes, I agree with you. It will be really a pain for the people in INDIA to sent those engine components to them. But tell me what about the people over there in USA?
I believe K&N have more costumers in USA than in INDIA. 90% of the INDIAN customers are having the vehicles under 10Lacs rupees. Then what about the vehicles over there in USA? They do even have products for LAMBORGHINI.
Experts says, engine wears the most during in its cold start, that means for the first 10-20secs. Do you Believe this?
Nobody will say 0W must be used only for the places where the temperature gets to freezing. Lower the cold viscosity higher the cold start protection.
I HAVE ALREADY TOLD YOU THE REASON FOR RECOMMENDING 0W-40,.
REPEATING IT ONCE AGAIN,
SINCE 0W-40 IS THE ONLY MOBIL1 FULLY SYNTHETIC ENGINE OIL WHICH IS AVAILABLE OVER HERE IN INDIA. I DONT KNOW WHETHER THEY HAVE 5W-40 OR 10W-40. YES THEY ALSO HAVE 5W-30, BUT FOR THE BETTER SMOOTHER IDLE FOR THE KB10 ENGINE, 40GRADE OIL IS REQUIRED AND THAT IS WHAT MY EXPERIENCE.
I believe I have some basic knowledge atleast for the kb10 engine oils.
Correct me if I'm wrong, you are Always welcome.
Whats the recommended grade of engine oil for Ertiga? Isn't it the same 5w-30?
I still cant understand why you are more conscious to get higher cold viscous oil even which is out of the range recommended by the manufacture. What benefits you get from it, can you please explain your view?
In a-star manual, it recommends plug replacement in 4years/40,000kms
Even the MASS forced me to change the stock plug only when i went for the 30,000kms service. So without any issue Its really useless to inspect the iridium plug with a mileage of 15,000kms.
"Kiran,I think you blindly follow whatever is out there.Try and understand what kind of usage these parts are intended for."
Listen, I will change my iridium plugs when they start showing any sign of weakness, I dont have any intention to use it till a particular period of time. Since most of the users have got a very good period of life with their iridium plugs, I'm also expecting it, thats all.
Jarpickle, You are very much confused with the "LIFE OF A PRODUCT" AND THE "WARRANTY OF THE PRODUCT".
K&N claims a warranty of 1,60,000kms and it still doesn't mean its useless after these kms.
For example: Consider a CFL lamp, most of them comes with a one year warranty, but it doesn't mean they are useless after an year.
Similarly it also doesn't mean a car is useless and worthless after completing its warranty period.
So if something goes wrong in its warranty period, you have the right to get it rectified.

If you want longer lasting spark plugs, try the Bosch +4 series.They have 4 electrodes and they last longer than single electrode ones.
You still have to clean them at regular intervals.
Really thanks for spending your valuable time to get me the right thread and post number :)
Jarpickle, Im really sorry to say, if these are the kinds of experiences you are considering to blame K&N then its really wrong.
"we had suspected after some running the washing solution left behind in the the airfilter was coating the sensors"
Here how can you blame the K&N filter. If the filter is not cleaned and oiled well ,obviously it will go wrong.
"I agree with "jarpickle" that most of this is down to mental HP(imagination),like a exhaust end can on a car can make you feel like its from The Fast & the Furious."
I didn't ever say you can gain lots of extra horsepower. But obviously its noticeable especially when you switch ON the A/C or when you are at higher rpm since the engine can rev much better with the less restrictive filter.
"Remember mild improvement in throttle response does not mean increase in power."
He agreed the mild improvement in throttle response. right?
Here the improvement in throttle response means when we apply the throttle, without any delay by wasting up the fuel, it shows the better combustion on your wheels. Yes that is the only thing we can expect it from upgrading the intake alone in a stock engine.
For stabilizing its initial cost, you don't even need to get an increase of 2 or 3 kms of extra mileage. Instead a slight increase in mileage(eg:- 14.17kmpl insteaed of 14kmpl) is enough to meet the price in long run.
PS:When I changed to K&N, the stock paper filter was fresh and clean. so the noticeable changes are genuine.
Thanks for the suggestion. I will check the Bosch +4 series.
