Was easy to install with instructions. When I first started the car there was no noise. Gave me more room than the factory tensioner that got in the way of my wastegate reset pipe. Things that might be helpful would be a small tube of blue caulk with product and perhaps a recommended belt tension adjustment. Neither was a problem for me, but maybe something will be added in the future. I haven't run it to 7000rpm yet, but I don't see any problems.
