Don't let anyone fool you. This filter is far superior to any paper filter.They last forever and give your engine the proper air flow,which in turn gives you increased performance and better fuel economy. I have used K&N intakes and filters for years and there is nothing better on the market today. Thanks K&N for the great products.

Got this for my 1999 454 7.4 motorhome. Also took out exhaust manifold and installed headers and Banks power exhaust. This made a NOTICEABLE difference. Just adding this filter I swear u can feel it sucking in air a lot better. So happy didn’t expect such a difference just from this filter but it def added horses. Good for the engine
