Car & Bike Ricer or sleeper ?

Baatli, not the replacement K&N Air filter but a conical one. It does make a difference. Yes, you have to retune your engine to deliver more fuel into the cylinder, but it's worth it.

these days for cars everything is controlled by ecu only na or am i missing something ? i read quite a few people saying that there was not much of a difference. and rather than going for a conical one it makes sense to go for a cold air intake rather than giving hot air to the engine. like for palio the filter gets air from under the car someplace so wont make sense removing that and putting a conical one.

also lazy people like me have no patience to clean the filters regularly :lol: and also if you forget to remove it before service the service people go zomg aftermarket .. that voids your warranty :lol:

also even with stock air filter there was lot of dust in the filter box dont know how bad the k&n one which has larger pores will be :lol:

well, i meant the stock replacement one only:ashamed:. And I read somewhere that K&N's dont help NA diesels at all, but forced induction motors get some benefit..
in the end , there aren't many mods you can do to a diesel. fart cannon? And then what , sound like a truck? Pete? he cant help. he doesnt do tata vehicles
weight reduction? I'd have to throw out the engine first

get some better ice man, why do you want to go faster with all the traffic around these days :lol:

plzz dont modify tata cars...they dont deserve it

stop making racist comments :bleh:

I thought the ECU will calculate the amount of fuel to be injected on it's own and if more air is going in, it will inject a little bit more fuel.

About the hot air part, I agree. Better to have a CAI.

After the tbhp meet yesterday, let me make a fool of myself once again. :ashamed:

Bottle sir,
A K&N doesn't exactly offer better breathability due to larger pores only, its the entire construction and principle of filtration that ensures so.
If it was only due to larger pores, it wouldmean more dust clogging carbs/injectors and then it surely wouldn't have been used in competitive events like MX, etc.
Also a K&N still has better breathability towards its service time than s imilar paper element stock filter.
Ya- one of the main advantages of K&N is that its reuseable and still as good a a new one.
Also it's not only about more air but having enough air when you demand it.
The engine should not gasp for air at higher rpms just cause the air filter is unable to suck in as fast as a bare naked intake valve can swallow.
So if the stock air intake system is poorly designed or restrictive, one can notice better driveability even in stock vehicles.
Also, in competitive situations, the frequent gear changes, high-revving and constant changes in pedal/throttle input may create blank spots because the air filter is unable to respond to the sudden huge inputs required every now and then causing ppor air intake and reduced performance that the engine can offer.
It's like gasping for breath with a open mouth instead of through the nose- more air we need and the nose cannot keep up na.
Regular users- no matter how gung-ho they feel when in their car/on their bike- are better off with the stock intake system though- for the costs, performance gains attained, service/maintenance related issues and for some other reasons too. :cool2:

I thought the ECU will calculate the amount of fuel to be injected on it's own and if more air is going in, it will inject a little bit more fuel.

If i am not mistaken and my memory serves me right, air to fuel ratio (and not vice versa i think) is always a set ratio for any vehicle.
It's the amount that varies and not the ratio.
The amount of fuel required for a vehicle at a certain rpm/gear/speed depends on the power theengine needs to produce to maintain that speed/momentum/acceleration and is almost preset.
What varies is the amount of air required to effectively 100% combust the fuel you pump in.
The amount of air depends mainly on the atmospheric pressure and some other factors too.
So all these values are preset into the ECU.
Now when one changes the engine dynamics and/or works on the engine, intake, exhaust, etc these values need to be re-calibrated.
Similar to setting the fuel+air screw while tuning the engine in a carb-based vehicle.
More fuel getting drawn in doesn't mean more air will get drawn in unless the engine is retuned- be it setting up the carb or remapping/re-chipping the ECU if need be.
