This is a nice NOS #13716 Soft Plume Fogger nozzle.   The Soft Plume Fogger nozzles' unique flow design provides better atomization of supplemental fuel, as well as more even fuel distribution within the nitrous flow, than other types of nozzles.   Changing power levels takes only seconds and is simply a matter of changing the fuel and nitrous jets on the nozzle; can be jetted up to 150 HP.     Includes NOS .018 and .026 jets for the 35 HP rating. 

Barely used; nice shape---------guaranteed 100% functional and leak free.   Fixed shipping of $4.00.    Current Summit catalog price on the nozzle alone is $55.95.     See my other auction items for more good deals on nitrous and hot rod parts--------------you can also call the shop at 702-596-2616 with questions.
