After extensive testing with a K&N drop in and a paper filter, I have come to a shocking conclusion. A new drop in K&N filter makes more power than a dirty 30k mile old paper filter. At least my butt feels the car is just a little bit quicker, and power doesn't nose dive in the upper rpms badly as before. It feels more like when I first put the H-pipe on (had a clean paper filter then). As for gains with the K&N compared to a clean paper filter, no idea, but probably no noticible gain.
Sorry to disappoint if you expected this thread to have any technical merit. This thread is infact, completely worthless.

the only reason I have my K&N CAI is that it only cost me $85. otherwise I would have kept the stock snorkel removed with a K&N drop in with an aftermarket intake tube back to the TB.
