Well, I finally took the time to install upgraded D2S HID bulbs. It involves removing the bumper and headlight assembly. So I thought I'd walk everyone through it. Let me know if I forget anything.

Things you'll need:
10mm Socket wrench
flat head screwdriver
philips screwdriver
philip head drive bit
garage ramps
spotlight

Time 2-3 hours.

*NOTE: Since you're removing cosmetic materials (bumper & headlight), be cautious not to scratch either while doing this.

 

Remove 2 bolts and 3 clips on top of the front bumper

 

Remove the non-marked clips by prying with flat head screw driver. Pop up 1/4" and you will be able to pull the entire clip out.

 

what else you need to remove the bumper?

 

nice write up... i was planning on doing the same thing. good job bro.

 

Under each wheel well, remove 1 bolt and 2 philip head clips.

 

I used a philip head drill bit to unscrew the clip. You may have to apply no pressure in order for the threads to catch.

 

Next remove ~10 philips head clips right behind the black plastic lip. You shouldn't have to remove any other clips holding the under carriage.

 

Now unscrew the two bolts holding the intercooler screen.

 

What bulbs did you upgrade to ??

 

Now slightly pull the bumper down on near the wheel to 'unhook' a tab, but don't yank off the bumper just yet.

 

You'll have to disconnect the intercooler spray tubing. Near the driver side headlamp on the bumper, you can disconnect the tubing from a white coupling.

 

With the bumper slight pulled forward, get underneath the vehicle to reach and pop off a clip holder for the tubing. You will need a long skinny fork like tool to rock the clip loose.

 

Now you should be able to carefully pull the front bumper off.

 

Starting with the driver side headlamp....
Remove the clip on the inside of the headlamp. This will allow you access to one bolt. Unscrew the two top bolts. Remove the forward most bolt near the wheel. (4 bolts total)
