DO ANYTHING BUT A SPACER ON A 4.7. YOU WILL GAIN NOTHING BUT A VERY LOUD, DISTURBING WHISTLE. FOR WHATEVER REASON I TRIED ONE ON MINE AND WAS BY FAR THE WORST THING I HAD EVER DONE. IT WORSENED PERFORMANCE AND GAS MILAGE AND MADE THE ENGINE RUN LIKE CRAP. IF YOU WANT A SERIOUS IMPROVEMENT ON PERFORMANCE AND FUEL, GET A COLD AIR INTAKE. THE 4.7 LOVES THIS.
