Between the factory standard Air cleaner and the claimed high-capacity Air cleaner? I believe the factory option code is (K47). Been curious of this and never known the differences. Does one actually draw more air some how? Is there anything to be gained from the swap, if you wanted to stick w/ a factory airbox?

 

The high capacity air cleaners are intended for use in dusty conditions or diesel/ HD applications. Basically it gets a larger air filter to allow it to be used longer before replacement.
