This performance cone shaped filter is about 1 1/2 inches deep on the filter part and about 1 7/8 inches in overall length. The opening where it fits onto the carburetor is about 42mm in diameter.
This type of filter is easily washed and completely reusable. It is considered a performance filter because it allows more unrestricted air to enter the carb which in turn makes the engine more efficient. If your dirt bike or ATV does not have a filter similar to this one it might be a good upgrade for you.
