Well I didn't see this in any other forum so I thought I would add it. I just put mine on and they seem to give a little bit better midrange in first and second, but the heat and air conditioning slows down a little bit when I come to a stop. I didn't notice the lights dimming or the change in idling that is associated with this kit. However, DO NOT buy the so called "underdrive" kits that give you a crank pulley, I have heard a lot of bad things about this pulley and I recommend doing the power steering and air conditioning pulleys only. And I have a 97 Accord with an H22a.
