K&N Air Filter, the side effects.

ScarySkulls · 5th June 2007, 23:03

Dont worry. Will work good buddy.
There is nothing like a bike filter or a car filter. Same material in different packaging. That's it.

So if a UNI meant for bike can feed a turbocharged engine, it should be good for your track king Baleno also.
Makes logic? or do I owe an apology? lol

Doesn't the size of the filter matter too? Too tiny a filter and it could choke your engine. And the size of the Uni's that I have seen are rather small. I hope my point makes some logic too

. And no this filter was not running on a TCed engine. Not that I know off unless you are talking about Ron's car. But, I havent noticed what filter he used.

One of the bhpians once posted a thread on BMC air filters. I searched the net and came through some positive remarks about it.

highwayblaze · 6th June 2007, 00:54

I have a BMC air filter on my Suzuki GSXR and a K&N on my GOLF. It does a great job as opposed to a stock filter. I think the bottomline might be where and how you use those filters. Its like using a Cold Air Intake in every type of weather even when u'r not supposed to. Like in heavy rain or snow areas. Obviously the engine will eat dirt water moisture all that.

God knows where those guys did the tests? In a desert? On regular city roads or what? All this factors in. Formula 1 does not need K & N to teach them air - filtering. Everything off a F1 car is specifically made for that task. Same with Mugen or other tuning companies most of who's cars are turbo charged and have those ultra massive conical or bulbish filters which i'm sure are pretty similar in construction to a K&N and hence should render similar damage. You will see other race series that use K&N.
And on what basis do you say that they don't use K & N in their NA cars?
Draw a line between "performance increase" and "tolerable dirt level" in your engine and design a filter. Thats what these after market guys have done.

Nascar uses KnN, so do some high performance cars like the Catram et all.

highwayblaze · 6th June 2007, 01:13

Many racing cars/trucks/motorcycles use k&N here's a few links!

And here's a link "Can a better air filter improve fuel economy" and other stuff on this link.
Can a better air filter improve fuel economy? We'll find out...

I guess Ron's car will be using UNI only

And how about we end this discussion and come to a conclusion that whatever the filter, just get a UNI wrap for it? hehe.

EDIT:- Aye McLaren, find anything useful here? Automotive Air Filters

Rtech · 6th June 2007, 11:02

Uni only makes a few filters for cars. No OE fitments. Pipercross makes those. As mentioned though, you can simply buy a sheet of pipercross/Uni foam and cut it to the desired size.

Some people above have mentioned nascar. In motorsports, ideally you wouldn't run a filter if the air was perfectly clean. But, as they need to have some sort of protective barrier from larger objects getting into the system, they use the filter which allows the maximum flow.

Its simple really. You can't have your cake and eat it too. If you want more air, you need to either increase the surface area of the filter or fit a freer flowing filter. With the latter, you will have to sacrifice some filtering properties to get the desired flow. Fine on a relatively controlled and clean race track, but not the best on our dusty roads.

Ask yourself this, what do most offroad/Baja racers use for filters? Majority of them use a foam filter. It's found to be the best compromise between filtering and flowing. BTW, K&N themselves recommend a wrap when their filters are used in dusty conditions.

ScarySkulls · 6th June 2007, 11:13

Nice post Rtech.

I dont have Any experience with Pipercross. How would you rate them buddy?
Do they make any OEM replacements for Indian cars..??

Of the two ideas that you mentioned, the first one (bigger airbox) is also a nice one.
Anybody you know who tested it?

mclaren1885 · 6th June 2007, 11:18

So, you guys are saying just wrap the Uni foam onto my K&N? I will be happy if that is the case
