The Kayfun Monster V2 is a Kayfun on steroids. It has 4 massive air holes and pretty large juice channels as well as the air hole that comes up under the coil. This is one airy beast. Other than that it is essentially the same as a regular Kayfun. It still fills from the bottom via a removable screw. Also included in the kit is a mini tank section/topcap and a bell cap.

The center pin and block are one piece that is gold plated allowing less voltage drop and much more airflow due to the airhole size
