when the filter is on the truck it cuts out completely almost dead silent but if i take the filter off it runs great perfect in fact. the filter is 14 inch brand new i just rebuilt the engine 1972 4 barrel 350 medium cam but still has STRONG vacuum and its bored 40 over i don't get it the
vacuum advanced is perfect timing is set correctly i have double checked and the choke is staying open in fact its wedged open now the wiring is perfect i have worked on these dang Chevy's since i was born this truck stumps me
k&n filter with the top that breaths too its New new and works fine on my 1975 350
pure aftermarket open filter for all to see
fram has horible flow and not very good filter element i have a flow bench i cant figure it out
just to be clear it flows better than any other filter combo on the market it should be geting plenty of air
