Common air filter adapters are flimsy and weak. This causes the filter to fall off the carb during off-roading or during assembly when trying to tighten the air filter nut too tight.

• This 3D printed heavy duty adapter is extra thick and sturdy. It has a larger filter lip for holding the metal air filter base and thick gussets to handle heavy tightening of the cap nut.

• Gussets can be rotated to clear the fuel hose and throttle linkages.

• The adapter accommodates an air filter base hole opening of 5-1/16” to 5-1/4”. Application of sealant on lip for an airtight seal is permissible. Material is ABS.
