Well, I am about due for my first air filter replacement. Last week I installed a do it yourself cold air intake in the filter box. Which drop in filters do ya'll recommend or should I just go back with the stock filter?

Here's the one I use; Amsoil EAa189 https://www.amsoil.com/storefront/eaa.aspx. It does not pull down the filter-minder. Check it out.

 

I've drilled my air box; and get my all my filters at geno's in the 4-2-1 package: 4 oil filters, 2 fuel filters and 1 air filter.
