$25 shipped to lower 48 2"/50mm Diameter CNC aluminum. 1.22" center to center bolt pattern. I made 4 but 2 are spoken for. 044/046 I will supply 1/16" thick gasket material for you to cut your own so you don't have to modify the backing plate. Here is a link for a filter that should work. http://www.amazon.com/Uni-UP-4200AS...id=1423095823&sr=8-8&keywords=50mm+uni+filter
Actually I don't know. Some crazy member asked for one so I made a few extras. I would imagine air flow and velocity is better. I'm definetly going to put one on my 056 mag cause they have horrible flow and filters.
That's what the west coast guys were calling those green filters that they run on the velocity stacks.
Oh, I'd be interested in one for an 056 if you get around to making extra! I agree, the stock setup is terrible.
prell 73 a few issues, but can be done. I would have to make one shorter and 1.875" diameter so you could buy a K&N that has a 40 degree elbow. Also look at 3rd pic. If your carb has the snorkel on top you will have to get the older diaphragm cover like shown on the left carb.
