02 mine motor A

Hey there, 

I've got a stock air filter thats busted up at the base from the previous owner's hack job adaptation to a 32/36 years ago. I would like to do the ITG setup on my 32/36 water choke carb and was wondering which filter element did you go with? Looking on Pegasus there are a few different sizes available and didn't want to get too big or too small a filter. 

Thanks!
