i might have to do some testing. carb shop near me has a flow bench take my stock ats setup down with some filters(ford, wix, k&n) dropins and see what is better flow wise.
Model 093
I paid $15 for my Wix filter. I think for stock boost level's they are okay, if we push a lot they dont do great. I took my old filter out and the paper filter was real ditry. Definatly going to run a different setup soon.
