The installation "tool" is a plastic cover that fits over the cam sproket, and has a slot in it where you break the chain. It holds the chain on both sides of the break, and has a lip that guides the old chain out. Very spiff.
Makes life somewhat easier for the mechanic -- my mechanic says it cuts at least half an hour off the time required.
I suspect the preformance products part is the same or similar.
