I had to turn a couple of clamps (ends) to have room for the extra width of the throttle body spacer. You may knock off/separate a coolant line underneath by accident but it's no biggie very little will run out and you just oush them back together. I didn't get a whine that many say they get. I didn't notice any extra power. The TBS itself is made different than for some other engines. The TBS pictured its thicker and provides more space to get a better response.
