No horsepower/torque gains, but I think this will prevent a loss in tq/hp. When the IAT and MAP sensor gets coated in oil they can start messing with the the ECU. Because of the oil coating the sensors, the caibrations/readings from the sensors can be read improperly by the ECU and this can cause the ECU to pull timing from the engine or screw with the AFR, resulting in loss of hp/tq. I hope I explained this correctly.
