so why a lid?
**** sorry, I gained with the K&N the paper was new and clean, the K&N was used and dirty. But on a 3 pull back to back it picked up each run, it picked up a few from the first run to the second with the paper filter and a little more on the last run with the drop in K&N, glad to see you did your own testing too, its weird we have different results, but even more interesting is the small gain/loss between the two filters, guess paper isn't all that bad after all.
here is the numbers/filter and runs numbered in order. being as there is a pattern here I dont contribute it all to the K&N necessarily but it definately did not lose power.
1. 295.4hp 308.7tq /paper
2. 298.3hp 311.2tq /paper
3. 299.9hp 313.6tq /K&N
Aren't most dyno runs post different numbers even if they are back to back? It woul dbe hard to actually measure if the K&N differs from teh Paper. I like how I can not spend money on a paper filter every XXXX miles, all I have to do is clean teh K7N which take a few minutes and slap it back in. Paper filters are just fin if you want to keep replacing them.
