Cold Air Intake CAI for my AE111

Hi all, long time I've not update any progress done to my car. So here is another mod. Cold Air Intake or CAI.

My engine still using normal air filter box, if i can avoid hot air goes into combustion chamber I can gain extra power from it. CAI is not use to eliminate hot air, but is use supply colder air to air filter.
The theory is, colder air contain more oxygen. With more oxygen, engine can get near to perfect combustion thus can produce more power.

I do not show how to remove the bumper in this thread.

First thing is remove the white part. Need to remove 2 screw and loosen 1 screw as per picture below.




Then make a mark as I need to make the hole larger to fit the CAI hose. I use stone bit and grind it until large enough to fit the hose.




I just drill the hole just fit enough the CAI hose. So, to fit the hose in, I turn around the hose like fastening a screw. 



My little assistance doing his job.



How it look like after fit back the bumper

  1. Hi bro, nice one.

    Since the hose is not connected directly to the intake, I guess the air sucking power is not strong enough to suck in water, which is good. Maybe you can test for a while and provide a review about that.

  2. Ultimately cold air is better because it will expand more when it combusts. The warmer the air, the less it will expand when in the pistons. Therefore, chilling air allows for the maximum combustion, which in turn will create more power.

  3. Cold air is just better in general. Nothing runs good hot! Even in at school, my college needed air conditioning repair in Westminster, CO. It was so hot for about two weeks before they got the problem fixed.
