Stock Component Removal

Remove your intercooler

It may be worth spraying down the bolts with a penetrating oil and allowing them to sit for a little while in order to allow them to come lose more easily without any breakage.

Using your 10mm socket remove the two bolts from the driver's side of the heat shield.
Followed down by the one on the rear passenger's side.
And the two low down near to the passenger's side frame rail.
With those items removed you can now remove the heatshield from the car.

It may require re-clocking the transmission dipstick in order to have the clearance needed to remove the heatshield easily.
Now is a good time to check out the heat shield bracket as the factory units are quite prone to cracking and damage. Replace yours as needed.

Turbo Blanket Installation

While we show what we feel is the simplest and most secure way of wrapping the wire and using springs to secure the turbo blanket there are many different possibilities and options that will work. Just make sure you aren't interfering with the wastegate or any other moving parts.

Start working the blanket around the exhaust housing of the turbocharger starting by working it under the wastegate arm.
Now tuck the other side down around the turbo and under the bracket.
Using pliers, hook the spring onto one side of the rivet, then work it around over to the other side under the up-pipe flange before latching it over the other side.
If using safety wire pliers, twist the wire on the rear rivet to an appropriate length.to reach the other side. If you're using normal hand tools do your best to get the wire secured tightly to the initial rivet.
Attach it tightly to the otherside either routing the wire underneath the downpipe or underneath the up-pipe if you so desire. (not between the flanges to block the gasket though).
Now that you're done you can put the heat shield back on if you so desire.
You're all done! Go out and enjoy!
