The Trasher CAI will NOT fit a bonneville. The high speed fan switch and harness will, but it'* really not going to buy you much if you just go with the 180° Thermostat and tranny cooler. Depends on your preference for heat damage insurance!
As far as the CAI is concerned, there'* differing opinions on just how much performance change there would be. I'm going to build one for the ADTR intake that will fit a Series 1, but probably not a Series 2. Really all you need is a heatshield below and on the radiator side of the intake. This forces the air draw from behind the headlight and in the fender.
