Air Temp Module?

"Gain 5-7 HP for your Camaro, Firebird, Impala, Caprice, Front Wheel Drive W-Body or truck for under $30.00! SLP designed this plug-in module that attaches between the air temperature sensor and its harness. It "advises" the PCM to provide maximum spark advance (1 to 2 degree increase) yet still retain proper knock sensor and engine function. Designed to fit most 1993-2001 GM cars. Installs in minutes. OFF-ROAD use only."
