Scott,

The Banks Ram Air Intake Part # 49194 is not designed for the P-Chassis, however, we have successfully installed one before with modification. The difference is in the tube going up to the throttle body. If you take a heat gun and warm up the tube, you can make the appropriate clearances for the tube to fit. Please note that this would void the warranty on the system as it was not intended for use on that vehicle and once modification has been done it is not returnable.
