It snugs down just fine and seals alright - but, with the seal on it, the lid cover just seems to sit up higher prior to tightening it down.

It just seems like they are not necessary (although I did install them and am confident in the seal as well as my installation).

I assume the original filter's built-in gasket is a little larger than the K&N, thus the need for the new seals.

The installation is 99% fool-proof, not much you can mess up...Just thought I'd ask if anyone knew why K&N felt they were required.
