I just installed a set of Z Therapy SU carbs and decided to go with a cold air intake setup.  I didn't have any air filters so thought this would be a cool setup.  So I bought the air box from Unique Z products (99$) and the Spectre 3 inch chrome covered plastic piping with filter (80$) from O Reilly parts.  Very tight fit going thru the 3 inch hole near the radiator.  Should have opened that hole up a bit and not scratched one of the pipes.  I plan on moving the horn to the other side and rigging up a standoff clamp to go around the pipe.

You're ready for summer.

That's really cool!

Great job.

Bruce from Z Therapy highly suggested the cold air intake setup.
