Stihl Vstack fits 044 through MS 660. ( does not fit MS460/046 or MS441 )
Easily installs on your chainsaw in minutes, takes a 2" I.D. air filter of your choice.
I recommend Uni-Filter PK-82 Black Pod filters, Uni-Fitler U-402 ( Green Weenie ) , or Uni-Filter UP-4200AST Clamp-On Dual Layer Pod Filter and Bel-Ray foam filter oil.
This application works excellent for milling applications, burn cutting, or just general cutting.
* Comes with a small piece of foam to put into the carburetor inlet *
Note: The air filter cover will not fit back onto the saw with the use of this product.
