Okay, I'm a newbie to this so I hope I'm doing this right. My buddy has an '05 Corolla S and was thinking about installing a CAI on it but wanted to know if he would be voiding his warranty? He plans to get a professional to do it but not the dealer. What do you guys think? Another thing, The console lights are the standard green color and he wants to change it. Where would he be able to get different color bulbs for it and what size would they be? does anyone know or have suggestions? If you could help out, I'm sure he would greatly appreciate it. Thanks!
