The parts are of good quality and I would advise that if you have not worked on a Throttle Body before you may find this tough. I have work on Throttle Bodies as well as carburetors and this one due to the spring pressure has its difficulty. Once together I bolted it up to my intake and cranked the Truck on the second try. It runs very well and seems to get better with each time I drive the Truck. I can't really say much regarding the horse power increase but i do think that my truck is running better and as well as seems to ideal much smoother.

but the transmission went out the day after I installed it so was not able to get a good feel for it
Works well as far as I can tell, but the transmission went out the day after I installed it so was not able to get a good feel for it. Installed easily though.
