Chuck! You are my hero! This is the exact oil bath air filter I have on my truck and I just started down the path of switching it to a paper filter. You have now supplied me with the NAPA part number without the headache of trying to figure out which filter will I have to use to make this work!
BTW - Now that you are running with this setup, did you have to make any carb adjustments to dial it in or was it a simple swap-n-go?
