Our Internally Vented "IV" Gas Cap is made in USA from 6061 Aluminum. With a performance look in mind. These caps will fit all HD Models with standard screw in style gas cap.
To help prevent tank splash we threaded in a Brass mesh splash filter and added a strong rubber O-ring to make a solid seal.
** The "IV" Gas cap CANNOT be powder coated as it will seal up the venting hole **
** Does not work for Dummy side or Fuel Gauge Side **
**SIDE MOUNT TANK OPTION COMES WITH 1/4" NPT PLUG IF NEEDED**
