I helped a friend put a Luk in his father's 94, the cost was well under half of what he could get the dual mass for. I never noticed any noise, and they never said anything. BUt his dad got back after we put that in, and he acme up to me kinda like pissed off, and said "what did you do to my truck?" Of course I didn't know what he was talking about, and he then let me off the hook saying" I t has more power than it ever did!" He was just kinda picking on me. The Luk flywheel has some more mass to it, so the torque it gives gives the impression of more power.
