I was wondering if anyone has removed pieces like emissions controllers, air pump etc that could improve performance and clean up the car under the hood. I live in Canada so I can remove such articles however I do want to be able to re-install them if need be. I seen pics of someone how had removed the air pump and changed the air filter to a cold air and man it looked good under the hood! Any info would be appreciated. Thanks P.S I tried to look for threads on this but the search didn't come up with anything.... maybe wrong words.

 

You didn't find threads in your search because there are entire sections of websites devoted to things like this.

Do some looking around there. I'm too tired to list everything.

 

air pump, a/c, power steering, AWS, AVC, etc. etc. etc.
