I'm looking for any input on these little critters. I recall some kind of post about them here a long while back. My only other experience is a friend that used them in his old WS6, and new GTP. I'm in need of replacing my O2s, and am debating if I should try these or not. Justin '92 SHO in KC MO, 190k and counting SHOTimes list info: http://www.shotimes.com/SHO1.html
