K&N vs. Green Filter
So I have been running K&N air filter for years without even thinking about it. A couple days ago a friend recommended a new filter called Green Filter air filters. So I want everyone opinions on it. Below are the links to K&N Filters and Green Filters. Let me know your thoughts and opinions.

might be better but if you've already spent the $$ on a K&N, why would spend more $$$?

My preference is green filter but I doubt you'd notice a difference between the two. Not worth changing imo
Is this in the stock intake or an aftermarket?

JacFab did a test of all available filters a few years back, and neither of your contenders placed. It is buried somewhere on C5.

Guess again. Green ,S&B and K&N flowed the best of all the filters he tested. And the 3 filters weren't that far off from each other for percentage over stock. 22 cfm between the K&N & Green filters

So Green looks like it performed better but the fit and finish is ranked at the lowest. Hmmmm.... interesting. I wonder how well they hold up over time?

I contacted the company yesterday and they said they use stainless steel for the frame of the filter so it will not rust over time.
