K&n intake different for turbo???

[BoBbOrAzE]

Hi i was looking to buy a k&n intake with the adapter for my turbo
on ebay the filter classified under the turbo only is roughly like $55 and the filter for the non turbo only is going for only $33. Given i need the adapter, still why would it be so much more for the turbo intake? I didnt even know there was a difference in cone filters for turbo and non turbo. is there?

The only thing I could figure is that the inlet for the turbocharged car is larger. Or it might have something to do with the mass airflow sensor differences (if any) between a turbo and non-turbo.

I recommend the K&N ripoffs. Hard to beat $20 for the same thing.
