yeah its a hill power kit - basically a RamAir filter inside a heat protective shield - its really good - makes a decent sound, not as loud as a K&N etc but still good, plus it looks great. Still debatable whether any power gain etc but I like it and did not notice any power loss over the K&N or Pipercross that I had before this. Put the K&N on after about 100 miles so no idea what it would have been like with panel fitler as did not boot it until 700 miles (running in)
