Hi All,
Just registered for NICO, and wanted to say hello. Just bought a 2013 CPO Infiniti G37x Sedan for my wife, she is very happy. It is our very first luxury type car and I have to say it strikes the right balance of luxury vs performance, especially for her. I would have preferred the Coupe but it her car.
My car is a heavily modified 2004 WRX, so I am for better or worse I have the mod bug. I downloaded the Nismo catalog, I cannot tell from their VIN designation which engine I have. Is it a VQ37VHR? And in terms of not voiding warranty, is a CAI okay? Will it gain any performance without a tune? I know if the car is MAF based it may be an issue.
Thanks!
Hello!

Re: Hello!
Welcome to NICO!
I'm not certain, but I think so long as the parts are Nissan (NISMO) specific, they shouldn't void the warranty. However, that being said, modern cars are very sensitive to any changes so a tune might be in order and I'd guess that would void the warranty. I'm no beacon of knowledge on the subject though, someone else may know better.

Re: Hello!
You're correct that the G37 has the VQ37VHR.
I don't remember the specifics of the law, but modifying your car cannot void the warranty. If there is an issue, the deal has to prove that the modification caused the failure. This was primarily enacted to prevent unscrupulous dealers from getting out of warranty work for non-related issues, ie; they wouldn't cover a failed radio under warranty because you installed a CAI. That being said, the general consensus among the aftermarket performance crowd is to keep all of your stock parts, and if it has to go in for warranty work, to put it back to stock before taking it in. It just saves A LOT of drama. That being said, a CAI is incapable of of causing any engine damage, and if you use NISMO parts and have a dealer install them, they guarantee not to cause any warranty issues. This is something your local dealer may not be aware of, so you may have to contact NISMO of N.America and get some documentation to provide to the dealer if they give you a fuss.
I don't know on that engine if there's going to be any performance gain. Generally, most modern car's intake systems aren't very restrictive, so the gain is mostly from a driving pleasure standpoint as all CAI's increase intake noise heard in the cabin.

Re: Hello!
I've moved your topic to the G35 and G37 Engine, Drivetrain & Tuning Forum to get more input from G37 owners.
The warranty law float_6969 was referring to is known as the Magnuson-Moss Warranty Act. He pretty much described it in a nutshell. Here's two links that will give you a better understanding of the Act, if you're interested.

Re: Hello!
Thanks for the welcome. I post on NASIOC (North America Subaru Impreza Owners Club); it can be a rough crowd at times, so far NICO seems a bit more civilized, shall we say?
Anyway, was also curious as to whether there's any difference under the hood between the sedan and coupe; in other words, if a part fits the coupe, does it fit the sedan? I probably won't go too far until the warranty is over, but my feeling is a starting point for power increase is to reduce flow restriction, so CAI, exhaust header, high flow cats and exhaust are the beginning. So far I've seen Stillen make such parts. So I'm curious to hear from anyone who's gone down that slippery slope...

Re: Hello!
We run a pretty tight ship around here. People come here looking for help, and everyone tries their best to pitch in. Those looking for trouble are shown the door.
I'm not too familiar with your particular vehicle, but I'd say a fair amount is cross-compatible. If you look at my signature line, you'll see a link for all the FSM's we've managed to collect. They're available free of charge for all members. The Sedan and Coupe are there, and it's a good starting point to solve a lot of problems.
Honestly, sometimes the easiest and quickest way to check cross-compatibility is to perform a Google search using the factory part number. Don't be surprised when the result comes back saying the part is also used in your vehicle and the Nissan Murano.
