A very good question indeed. I am myself trying to find the answer to this question for some time now... I know of lot many people who used it in petrol cars and they say you can expect a realistic increase of 3-5% in the torque figures. However thats about it. Not many with diesel car experience. Moreover whether a good alternative to K&N exists. I know Ractive also makes these filters... but then how good are they vis-a-vis K&N? Again I am not so sure... Would love to know some definite answers on these lines though. My Indica can also do with some low end grunt.

Yes, K&N filters do help. It would definitely help on a normal TD like the Indica. When I ran it on the Baleno on track, there was a definite improvement in the car's performance.

Yeah agreed about Baleno. The problem is Baleno also is a petrol. And petrol cars do benefit from a K&N as many seem to suggest. But is there a conclusive evidence (read sizeable data) that it helps a ID diesel like Indica?

A better filter always helps the car to breathe better resulting in better performance. Don't expect a lot of change, but yea the difference should be noteable.

I use an Ractive Conical filter in my diesel sumo.

I fixed it when i was doing it up with new paintjob, body-kit,etc..

So, after not driving it for 3 whole months, it is not possible to note a difference. But, it sure growls like a lion.

I'm plannning to go back to the stock filter setup for sometime to notice the difference in performance.

Btw himanshu,u might lose warranty if u put a conical filter in. I don't know if there is stock replacement filters for Indica.

fitting a k&n on a diesel does not produce a great change, you could go in for the stock replacement instead.

my friend had one installed on his qualis, which was used as a taxi, slight improvement in mileage and slight improvement in pickup. so it would be VFM is you use a stock replacement instead of the universal kit.

A stock replacement K&N will be useful in the Indica.I've installed stock replacements on a N/A Indica & a Turbo charged one...both cars have become more smoother and low end pick-up has improved slightly.And yes,technically you'll void warranty if you use any other filter other than the OE units,whether stock replacement,conical,K&N or otherwise.

If you compare it to a old oil based wire mesh filter of the Padmini the new fangled filters are restrictive. The free breathing of the K&N matters only at high RPMs when the engine gulps in large quanitities of air and even then you would have to route your intake such that the filter is near higher atmospheric pressure and cold outside air which is near the front bumper in most cars at the expense of driving in the rain when there is real chance of intake water which is extremely detrimental to engines especially turbocharged engines. If you put your indica on a dyno you will see there is no gain in torque at low rpms as the OEM filters are designed for high rpms and therefore no gains in the lower rpms. If you want to improve torque at low rpm the only option is to go in for concomittant LPG injection:WTF:. Yes permanent LPG injection through a small orifice when the car is actually running on a normal diet of diesel. I do not mean converting the engine to run purely on LPG. Do a goooogling for LPG injection or LPG fumigation and your queries will be answered. The other option is to junk the Indica and go for a car with a bigger engine( second hand diesel lancer) or higher torque(wait for the swift diesel).Bye and wear your seatbelts.

Click on the title or copy and paste on to a new tab to know about LPG fumigation or lpg injection in diesel run cars. Bye and wear your seatbelts.

if u want low end torque you could think of installing headers. cause indica is the only diesel cr for which header works

Thanks a ton guys for all the Info.

guess the conical filters are out since they may void my warranty and have taken an extended warranty on the car.

Further, what I have gathered from your comments and experienes is that at low RPM, there is really ot too fiscernable a difference. so I am wondering wheher all teh expense will be worth it? Inany case, I am pretty satisfied with the top end of the car.

Maybe after a while, with the engine covering a few thousands more, i can consider a Pete's box fo rmy car!!!

Cheers

Actually any filter other than the OE ones stand to void the warranty. Another reason why I am a bit queasy about getting a K&N. Anyhow conical was never an option. And yeah K&N stock replacement filters are definitely available for Indica (somebody was wondering on that count). However unless the low end torque improves it is of hardly any use.

Hey Nitrous it will be great if we can have your comparative analysis between Ractive and the OE filter that you have for your Sumo. If Ractive also works effectively then that may be a better bet as the thing costs probably 1/4th or even lesser than that in comparison to
K&N.

Himanshu, Pete's box is not available for the Indi family of cars. I guess they need common rail engines. Unfortunately!

Do you have any comparative analysis or data to back that one up mate? How much is the improvement? Is it really discernible? As in, it won't help much if only a dyno can tell me that it is working... It should showup in actual driving.
