Air filter is clean, in good condition and was replaced about 5,000 miles before this, CAC we installed was not a cheap one. Is an aftermarket but good quality. I did replace back pressure sensor but not the Delta P Sensor, I will do that today. Did clean the passage way for exhaust back pressure sensor.
