Here is the proof: Air Filtration Test Hmmm, where actually is the proof there in this test? I can't find any proof there. So where is the proof? Obviously it is in the imagination of the reader, which is what the intention was when creating the article. Now my message to the morons: Try switching on your brain (it is the grey stuff between your ears) and use it. I am patronising? Not really, I am just fed up with having to read a lot of speculative nonsense from some all knowing all mighty keyboard warriors, who pretend to know about things when they don't and scare monger about things they do not even understand. In well over 10 crore of performance filters sold the speculation that performance filters, induction kits or air intake revisions have been the cause for engine damage has not been possible to prove true. Whether the filtration is better or worse does not make a difference. There is plenty of proof that engines have been running lakhs of kms with such filters ALL over the world in all the conditions with extreme dust as well and did not show any increased wear on engines. Even car manufacturers use them (Fiat group is one company!). If anyone wants to prove me wrong then bring up an article that proves something and not just a test that is subject of abuse. Any forum is not in existence to spout propaganda rather than enlightening the members about facts. A fact is based on realities and definitively not on the opinion of any member. Anyone who wants to 'sell' their opinion or speculation is in fact betraying their fellow members. And such people have no right to be part of any community. Before you comment on any subject that isn't a matter of taste rather than on facts remember this. People are respected for their honesty and not for senseless boasting.
