This is a new filter for 2020 - it is now a one piece boot. This air filter fits the Mikuni VM26 carbs that is commonly used with the KLX DRZ CRF 110 big bore kits. The inside diameter of the filter for where it slides onto the carb is 42MM. It may fit other carbs also but please measure carefully before buying. New clamp included. The front of the filter is flat to help clear your fender - we have a photo of it installed on one of our shop bikes.

These are a very nice quality dual stage foam filter to help with keeping your engine running smooth.
