Product Overview
This 45mm foam air filter is designed for larger 2-stroke scooter, mini motorcycle, pocket bike, dirt bike, and pit bike applications using a compatible 45mm carburetor intake connection.
The high-density sponge filter helps reduce dust, sand, and airborne impurities entering the intake system. Cleaner airflow helps support stable combustion, improved throttle response, and longer engine service life, especially on 2-stroke engines used in dusty or off-road conditions.
The 45mm size is often used on larger or modified 2-stroke setups, including some 70cc and 90cc applications. Please confirm your carburetor or intake pipe outside diameter before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This foam air filter may fit your model if your carburetor air inlet or intake pipe outside diameter matches the selected filter size. Fitment is based mainly on intake diameter and installation space, not only on model year or engine displacement.
Do I need to match the OEM part number?
No. OEM part number matching is usually not required for this universal clamp-on foam air filter. Please measure your carburetor or intake pipe outside diameter and choose the matching filter size.
What models or situations does this part not fit?
This filter will not fit 4-stroke engines, sealed OEM air box systems, carburetors with a different intake diameter, or vehicles without enough clearance around the carburetor area. It may also not fit if your original intake uses a special filter shape or mounting design.
What should I check before ordering?
Before ordering, please measure your carburetor air inlet or intake pipe outside diameter, confirm your engine is 2-stroke, check the available installation space, and make sure the clamp-on filter style matches your original intake setup.
