In my signature the 325hp was with no filter, with the paper filter it was 322hp. After the LT install I got 341.8 with no filter and 340.9 with the paper filter. I'm going to stick with the paper filter.

The K&N is made a little thicker in construction, other than that its the color of the oil like what was already posted. The Cool Blue is almost flimsy compared to the K&N depending on which part #s you compare(I sold both at the speed shop I worked at).
