With a built in dowel pin and precise inner diameter to make a 100% seal with the rubber grommet, this piece installs and fits as if it had a Mitsubishi part number. The system is then braced to the chassis with an aluminum bracket to ensure no movement or vibration. A single-piece mandrel bent 3in intake pipe makes the connection between the MAF and turbo with a smooth transition recirculation fitting for an easy connection to the BOV discharge.
