Hello im wondering if infiniti lets you modify your g35 coupe with out snapping your warrantie. I kno lexus does it i think with fugita and HKS. But if infiniti does let you what do they let you do and what brands do they let you do. I would believe stillen but not sure. ??

 

BY law they are not allowed to do that.... goolge the Magness-Moss Act

 

They cant void your warrenty unless they prove that the aftermarket part caused the problem. But people have been hassled before. Your best bet if you decide to mod your car is to find a mod friendly dealer.

 

Most Infiniti dealers will install NISMO performance parts and continue to honor your warranty. However, both the parts and labor are expensive.
