Hi,
Does replacing the intake from oem to R2C void the Infiniti original warranty?

Thanks in advance

 

mine didn't

but then again if you install new intakes and your MAF sensor goes bad dealership could come back and say your intakes did it

 

It does not "automatically" void your warranty but like ChinkyChoy said, if the modification directly impacts the malfunction, then the dealership can (and will) deny warranty work. If you're bringing in your car for a brake defect and they see you have an aftermarket intake, they cannot instantly deny warranty work on your brakes since they're not related. (Given that it would be covered by warranty otherwise).
