Woah, I had no idea this thread would come to this. I'm not trying to get $180 out of anyone. I just saw real world results with this filter. It's not that it gives you more power, it just frees up the power lost in conventional filters. No one has to buy anything. I'm not selling anything. I was just going to see if I can get the local dealer to cut me a break on a group buy and that's not allowed here. So, I'm getting mine soon and I'll report back what I find. I don't need any convincing. By the way, Boeing now uses their filters. Whatever filters were used back in the day are most likely completely different filters than the Pure Power ones.
