This Intake allows you to connect a 1.5" UNI filter to your GY6 engine with no additional mods.  You will notice on nearly every Buggy that the frame is directly in front of the carb. This bloks the ability to put a UNI or K&N style filter directly onto the carb.  This simple  mod allows it..... A must if you plan to do any mods including jetting and Muffler.
