Loosen the worm gear clamp securing the flexible part of the stock intake tube to the plastic section. Unlock the vacuum line fitting by lifting the tabs up and pushing them back. Next, lift the vacuum line up and out of the way.
Unplug the IAT sensor and disengage the tree clip holding the harness to the stock airbox.
Disengage the tree clip holding the coolant line from the stock airbox.
Pull back the flexible part of the stock intake tube from the plastic section, then lift the airbox assembly straight up to disengage the rubber grommets.
Remove the stock intake from the engine bay.
Install the Mishimoto intake coupler with 2x worm gear clamps. Leave the clamps loose. Note that the smaller end goes on the plastic intake pipe section.
Assemble the Mishimoto intake as shown. Fasten the bracket and CNC pegs to the airbox with the provided hardware, then install the rubber grommet and air filter to the rotomold tube. Push the rubber grommet all around until the barb fully engages with the airbox opening.
Remove the IAT sensor and the rubber grommet with a metal insert from the stock intake, then transfer it to the Mishimoto intake tube and airbox bracket. Next, line up the intake tube with the silicone coupler and lower the Mishimoto intake assembly into the engine bay. Push down on the airbox to engage the metal pegs with the rubber grommets.
Reinstall the stock fresh air duct and fasten it with the pop clip. Secure the coolant line tree clip to the Mishimoto airbox as shown.
