I know there are many dealers(Nissan and Infiniti) that are doing the Stillen S/C sale and install. They are keeping the vehicle covered under warranty as well, since it will be dealer installed. I just cannot find on local. I do not feel like driving to Fl just to get warranty work done. I ask Ray Catena and they looked at me like I had 2 heads. I know I can do it myself, but I am sure Ray Catena would not warranty my drivetrain incase something happens.
