so im running a SD tune right now with the stock air tube and maf still sitting there running into a slp lid with stock tb. keeping tb for now but want to replace everything with a straight silicone hose or piping into the FTP 104mm lid. I feel like this will be a pretty noticable gain. So i guess I need to know what the o.d of the stock tb is as well as the 104mm lid? the o.d of the ftp 104mm is 108mm. so something to connect 108mm to the stock tb which is roughly 80mm im guessing?

 

this is pretty much what i want to do except this guy had a 92mm tb i believe

 

come on anybody?
