Removing Factory Intake
Assemble the EVAP Line (click to expand)
For this vehicle you will remove the barbed fitting from the short middle bit of the pre-assembled evap line and install it into the loose length of provided hose. |
For this set of years you'll use the provided pre-assembled evap line. |
Using the smallest clamp (#40), install the 2.5" - 3" Coupler onto the turbo inlet and slip a #48 clamp over the larger end sticking up. Leave them both loose for now.
Make sure that your hose clamps are clocked so that they do not rub on anything. The ones on the coupler going to the turbo inlet in particular can be clocked in a fashion that they rub on other components of the engine bay causing damage. |
Once you're happy with the position of the tube, tighten down the hose clamps (8mm or screwdriver) followed by the bracket bolts that support the tube on the cylinder head. (12mm).

We found newer cars were more fairly likely to have the hood prop be in the wrong orientation when you go to install. Make sure it's oriented so that the prop itself fits into the retainer built into the radiator shroud. |
Install the supplied CARB sticker on an easily viewable space that won't be susceptible to large amounts of heat. We recommend on the radiator core support, or the underside of the hood.
