hi,

     I have an 08 FXST, these things run hot, I want info on oil coolers. I stumbled on to a product called a cool collar,

 does anyone have any experience with this product. On paper they look effective , inexpensive and easy to install .

    I have installed the O2 sensor mods from nightrider.com and am impressed with their effectiveness in cooling the engine and increase in power and torque but a few degrees less wouldn't go astray.

                                                                                                                                                    Thanks

Ductor,
