Questions

Does it require rain sock or special pre cautions while riding in rain ?

Asked by: Apples
Cover will do a good job of keeping debris and water out but it is not waterproof - also, K&N does not list any wraps for this filter. You might have some trouble if your city frequently has heavy rains.
