Make a selection 911110904WO Prevent costly air box explosions! Porsche 911 engines from 1973 on have had the bad habit of backfiring upon cold-starting. And blowing a hole in the air box. When this pop valve is installed in the air box and a backfire occurs, the valve will instantly open and release the backfire pressure. Afterwards, the pop valve then automatically closes and the engine continues to run. The air box pop valve conforms to all emission regulations and has no effect on performance or gas mileage.

Make a selection AP996TT155 One of the most important upgrades for the Porsche 996, Cayenne turbo or panamera turbo is to replace the factory Bosch diverter valves. The factory valves are prone to leaking pressure under increased boost when the car has an upgraded ecu flash. As well, the factory Bosch valves will taper boost off with the diaphragm design even at stock boost levels. To help keep the boost pressure constant all the way to redline, upgrading the stock diverter valves to the agency power racing diverter valve kit will improve your cars overall performance.

Make a selection AP997TT105 Adding bolt-on horsepower to the 997 turbo is a continuous quest by many enthusiasts looking for more power. reverting back to old tuning technologies, agency power has developed a larger throttle body and plenum kit for the Porsche 997 turbo to gain added performance. the point of a larger throttle body is to get in more air. The more air you bring in, the more power you make. The 997 turbo's engine intake system works off pulses, so how that air is diverted to either side of the engine is not as important as the volume incoming. General Fitment911 2005-08
