It appears to me the K&N filter used in our application has much less surface area [center section just plastic] with a circle of filter around it. Even if it flows better per square inch than the stock filter,,the stock filter has so much more filter area that I'm thinking there wouldn't make much difference.
Who makes the best stock type filter??

The LS 400 K&N filter has less filtering area than the stock type filter. The center section is not a filtering area ,just the ring around the center. It is most likely true that per square inch of stock filter medium does not flow as well as the K&N filter type BUT the stock filter has so much more filter surface area than the K&N. The center section is all filter. So for me It was a toss up so I just got a Purolator filter for the LS and passed on the K&n. Not all K&n filters are superior to stock.

There's a really good thread on benzworld.org where the administrator introduced k&n as a sponsor and this one guy just destroyed k&n with some scientific facts. check it out:
