Product Description
Puch Maxi air filter for bikes that used the square shaped type 17, 12mm carb, like the last Piaggio "super maxi".This air filter has a spacer so it will fit the original round Bing carb with a 20mm O.D. or the square carb with 28mm O.D.
As it has a 28mm opening, it can also be plumb up to other larger carbs.
