Air Filter for Chevy 12 valve

[KHaines]

Which are filter do you use in your conversion?

I have a 12valve in a 1993 K3500 with a K&N filter now. Do any of the aftermarket filter boxes work? What flows the most CFM?

If you have room for it, its hard to beat the 2790 from Napa. If that doesnt fit, the 6637 also works well. Although, there is a new Amsoil unit out there, which seems to be an excellent solution for air filtration, its the eaau4510, as seen in this thread...

I bought my Amsoil filter from Duluth Diesel with no complaints at all.
