I would strongly recommend getting the Hi Boy. You do not want the filter below the carb because of fuel that will saturate the filter. You will create a fire hazard. Now that you have the bottom bracket and the top cap you can order a K&N. Just use the Hi Boy fitting to the carb and put the bottom bracket on with a small piece of radiator hose.

Running an air filter will not restrict the air flow and richen the mixture provided it is the proper size to flow the CFM demanded by the engine. I used the long K&N which also meant I had to use a longer center rod. Worked great. If the carb leaks and most do you won't have a disaster waiting to happen. Small price to pay to protect your vehicle.

My opinion.
