Hi,
One thing to consider is that while these filters may flow more Air (at the expense of some protection from Dirt/Grit - the very reason you have a filter to begin with), virtually all pleated paper filters are capable of flowing more Air than their applications demand. So you have to ask yourself, in this case, if more is really better? This is where the compromises of less protection and shortened Oil Change intervals must be weighed.
These filters were introduced in 1969 by K&N Engineering, as a Long Lasting Filter, not as possessing superior performance. The company claimed that owners could drive for 50-100,000 miles between cleanings. This was their claimed advantage over Paper Filters. Only later, in the '80's, in an effort to boost sales, were any performance gains ever claimed...
Happy Motoring!... Jim'99
