In your opinion, does it increase power and mileage as advertised? Have you ever inspected the backside of the air box for dirt? I'm desperate for anything that'll make up for my larger tires. Given the non aftermarket for our rides, I'm willing to give every bolt-on, drop in item available an extremely hard look.
