I got it online for $120, install took about 45 minutes, due to the fact I had to cut, strip, and attach the loops to the end of each wire. I only used 5 ground spots. The hardware looks to be top of the line. Terminals and all other metal parts are gold coated for better connection. Id probably give this item a 8/10. I didnt feel any gains that I can tell of, other than a smoother idle and runs smoother in the high rpm range. Headlights are a little brighter. As for the higher gas milage that they claim, I dunno, cause my O2 sensor is bad.
