It pays to read installation instructions kids!). The only time they mentioned having to pay extra is if they had to remove a mod that was more than just a replacement part.

When I told my service manager I was installing the turbo I was specifically told they would no longer service my car at all even if it was a non-warranty item that I was paying for.

I went to the Infiniti dealer here that installs Stillen SC kits and the manager told me that he would cover anything under warranty as long as it wasn't directly related to the turbo install.

Short story long, it all depends on the dealer whether they give you hassle for mods.
