Modifications to do with existing warranty?

JARblue

Installing an aftermarket intake will not affect the transmission. Engine oil brand does not affect the performance of the differential. Those are not hard to prove.

But let's say you install an aftermarket intake and then start having trouble with a MAF sensor. Good luck proving it wasn't screwed up during the installation of the intakes.

I've done a variety of mods to my Z. And none of my warranty claims have been impacted by aftermarket parts or work. Others might not be so lucky. For additional details, research the Magnuson-Moss Warranty Act.

What modifications were you able to do? I have researched the Magnuson-Moss Warranty Act and this law is there to protect the consumer. The dealership service department will have to prove beyond a reasonable doubt that the modification/s caused the part to fail.I read that the Nissan dealership service department can’t just void your warranty because of aftermarket parts installed they can only void parts of your warranty claims if you have any. If you install a aftermarket cold air intake everyone here knows it will not make anything fail beside possibly your MAF sensor. A exhaust is not even covered under most vehicle warranties it is considered to be a wear and tear item. Installing Nissan Motorsports parts or Nismo parts are an option though true. This person said they are at the very least installing an aftermarket full length cold air intake and a aftermarket catback exhaust regardless of the warranty that was purchased. What it boils down to is there are some Nissan dealership service departments that are lenient about modifiying your Nissan 370Z and some are not. You will have to shop around for the right Nissan dealership service department to give your business to.
