For OG 9-5 petrol car, but should fit the OG 9-3 and probably any car with a 3" intake hose.

Put a tire valve in the hole. I used a TPS tire valve, but any should do.

Place it in the hose for the MAF sensor, disconnect and plug the vent for the cobra to PCV loop. Hook up an air compressor and hear all the boost leaks :)

PETG preferrable.
