"More bang for the buck"


This 235CFM inline blower was just what I needed To bring more air to my carbs due to their location.I have 4" hoses bringing air from louvers in the side of the bed but needed more air... these inline blowers work and fit perfect. I have a supercharged 355CI Chevy in the bed of a 1961 Corvair Rampside Pick Up.I have owned the truck for 52 years and had V8's for 44 years. At 82 years of "age when it's finished I'm finished". I am always trying something new on this truck.




great unit. works great, keeps dust out of helmet.


Use this unit on a Bell BR1 helmet. I ride a RZR 900. It really helps keeping the dust out.
