I have a 2010 Street Glide and getting the 103 stage IV screamin eagle kit installed. I bought a S&S dual runner intake that is supposed to fit a 50mm throttle body. However the screamin eagle kit has a 58mm throttle body. So as of now the S&S air cleaner is useless. I did see that the screamin eagle heavy breather fits both a 50mm and 58mm throttle body. Would I be able to use the screamin eagles backplate to install the S&S air cleaner or what about a JIMS 58mm throttle air cleaner backplate? I havent seen one up close but wouldnt the holes all match up? Any help would be great. If not then I guess I have to sell the S&S. If anyone is interested shoot me a PM. Its brand new and still in the box

 

anyone?

 

Not too many filter options with that, check with S&S

 

I did check with S&S and they said their filter wouldnt fit a 58mm throttle body. I am wondering do I really need a 58mm throttle body for the stage IV 103 kit. I switched out the 110+ heads for the cnc ported heads

 

I'll buy that 58mm throttlebody off ya if you want to sell it, pm me if you decide to

 

you definetely do not need 58mm for a 103 build like yours probably gain more with the dual runner intake read nuthen but good stuff on it. plus it looks great.

 

I have an Arlen Ness big sucker 2 that was on my 50mm and it bolted right up to the 58mm.
