I am about to install my AEM intake and in the instructions it says to disconnect the negative battery cable before beginning installation. Is this really necessary. On my last car I never did it, and had no problems. I have a tune on my car to so I dont know if that plays in somewhere. Need Help. Thanks.

 

i think that just so the computer doesnt act retarded but i have never had problems either so ?

 

No.

 

LOL, straight to the point eh Jimp!

 

i heard that if you dont the check engine light might go on...not too sure about this though
