Of course our expert Kris-know-it-all is right. By leting air in to the engine, we also let inpuritys int to the combustion cahamber. The best solution is therfore to close out all incomin air. That way mo impuritys get to let inside our engines.
And ofcourse K&N has stayed in the market by their clever marketing strategy, not because their products do what they promise. If our expert says so, it has to be this way.
And ofcourse an air filter that does NOT get dirty on the inside is the best. (Wonder where the dust goes if it does not stay in the filter?)
Of course, if it's on the Internet, it is the one and only truth. Google never lies and all non-scientific reserch is a proof of all selling companies being liers, trying to cheat us on our money.
From my point of view, everybody is free to use wich ever filter he/she chooses. On a bike with only 34 hp, the best performance upgrade is: Buy a stronger bike from begining.
I just saw your reply. with all respect, you have no idea what you are talking about. the dirt is not allowed to get to the inside of the air filter, but must stay on its outside layers. [email protected]
filters are crap, period. they are used by those who go on race tracks, and do not care about longevity of their bikes. many Harley guys put these filters, but it is more for the look than for their performance. otherwise their questionable benefits do not justify damaging your engine.
as for K&N being sued, no one can prove that the engine failure is due to air filter. it is an accumulative effect along many years. not changing engine oil, messing with exhaust, changing the fuelling system, all these things can contribute to the damage done to the engine. If you choose aftermarket parts, it is at your own risk. you cannot sue them because they are not approved by your manufacturer.
additionally, as I said, putting high air flow in the gs without changing the fuelling is plain foolish. you must compensate for the additional oxygen with more fuel, or else you will run too lean.
I do use 'K&N' oil filters, but they are not being made by K&N.
anyway, anyone can have their own opinions, but expressing them without doing a proper research is not right. you need to care about your fellow bikers...
