The top is a separate piece. Now you have two sealing surfaces to contend with.
I have heard of the same issues.
I do run the single piece ones on my quad and have in my cars.

What do you think the trucks in baja use along with some quads and bikes?
I could care less what everybody uses in baja. I use products based on what I have found thru research and real world experiences, not on what the quadtards in the desert think is best.

First I had to re-jet LEANER
I had constantly dirt / dust inside the intake manyfolds
Oil consumption increased, cylinder and piston and rings ruined!!
K&N = no good!
After the engine rebuild I use a Twin Air, no more dirt past the filter, lots cheaper and easier to clean. Forget K&N!!!
I asked my LandRover tuner about his opinion on K&Ns: "If you can look trough it, dirt will go through it.." rightly so!
I got in contact with K&N, cylinder and piston and filter went to the US (from GER!). Of course I had ruined the filter using "other than K&N filter oil" (such as Twin Air or No Toil), they send me a new filter which of course I never installed.
SAE has got a standard out for the performance of automotive engine air filter (do not have the procedure number at hand). Recommendation is an efficiency of 99,9% under dusty (=OR) conditions. K&Ns never make that! If you want, I can figure out the respctive procedure number. Contact them and ask for their results!!!!
