My response came from one source and one source only, ME. You don’t have to be a stinking engineer or a rocket scientist to look at something and then let common sense tell you the answer. To tell you the truth if you want to improve a K&N’s filtration you would add extra layers of protection like a pre filter (Outerwear) over the filter. It s made of a fine mesh that will stop sand and other debris, off roaders use them religiously. I have one on my EVO filter.

You can also install an oil impregnated sponge type filter that also goes on over the K&N, all for the same reason of keeping the filter the last line of defense against dirt.

As far as the OEM using a K&N or any other type reusable air filter. It’s all about getting money out of the consumer. You think Porsche or any other manufacture wants to sell something that can be used over and over than something that’s disposable that the public will have to come back for and buy? Please.

I applaud companies, like K&N, for making something that makes sense, saves me money and improves performance. If it wasn’t for those kind of company’s we would all have to buy our parts from the OEM.

I'm not a spokesperson for K&N, I just believe in and love the product.
