Old trick, is a .39 cent resistor in a fancy package to trick the computer into seeing a lower than actual intake air temp. This allows the engine to run more ignition advance. If it advances too much, you get knock and knock sensors likely will pull more timing than the gain from the resistor.
Does it work? Yeah, sometimes. Worth $70? No, save and get a good programmable water/meth injection system for real benefits.
