Well, although I have never done work on a car before (except for my oh so exciting M6 install), I decided to take a pop at installing the AEM CAI + water bypass onto my 2001 CL S-type.

This is a walkthrough of how I did the install, plus notes. AEM's instructions assume you have some kinda degree in car mechanics.
Click here for instructions you can print out and use for the install. They are brief, so you may want to print out some of these other pages which have more verbose descriptions/explanations.

You will need the following equipment:

  • If you have the bypass valve: Hacksaw and scotch tape.
  • Philips Screwdriver
  • Flat head Screwdriver
  • Socket wrench, with extension. (Mine was about 1-2" long")
  • pliers
  • 12 mm socket
  • 1/4 inch socket (optional).
