Took mine apart, like the instructions say, cleaned everything up, cleaned the wheelwell under the box, disassembled the intake tube, cut it, filed it, smoothed the edge, deburred a lip inside the box to smooth out the tube for better airflow, reassemled everything, shooting pictures along the way..... 25 minutes from hood open to hood closed - and I think I was slow.....
Pretty easy mod to do. Nifty sound, too. Plus combined with the 2° timing advance, it sure feels like it's got a bit more spunk!
