RED BEARD SAWS V-STACK ADAPTER FITS HUSQVARNA 298XP 2100XP 2101XP

 This Vstack adapter fits right onto the stock intake elbow. 

When you install this Vstack adapter, use the supplied nuts to secure it to the stock intake elbow. You can then fit any 2" I.D. air filter you'd like. I recommend a foam air filter, such as the Red Beard Saws Air Filtration System, or a PK-82, or the Green Weenie. 

This Vstack adapter will also fit other chainsaws, such as: 

2101, 298 and possibly others of the same 2100 chassis
