Be careful with the spectre filter because the metal piece at the end of the filter can heat up & burn into the wires that are right next the filter! This happened to me & I had to cut & rewire it. It does work really well for getting in a lot of air but if ur gonna use the spectre one I would recommend u cover up the cables with electrical tape!
