I FOUND THE FOLLOWING FROM THE FOLLOWING FORD PARTS WEBSITE: HTTP://WWW.1AAUTO.COM/1A/INTAKEMANIFOLDS/-/-/1AEIM00012. "THE ORIGINAL INTAKE MANIFOLD, DUE TO THE DESIGN, HAS AN ABNORMAL TENDENCY TO CRACK, LEADING TO OVERHEATING AND IN MANY CASES COMPLETE ENGINE FAILURE AND/OR DAMAGE TO OTHER PARTS OF THE CAR'S ENGINE. THIS NEW AND IMPROVED INTAKE MANIFOLD IS DESIGNED TO ELIMINATE THOSE PROBLEMS!".
