Hey guys, I'm new with performance part of Nissan. I've had Turbocharged Honda's since the 90's( which seemed simple) now days I'm selling Nissans for a living and love the G-35 Coupes!
But I'm having a hard time finding a good Air Intake System. So who makes the best cold air intake for results and sound? Do I go cold air or regular style? Or do I go with just a Stillen style Z Tube? Also is a Spacer worth the extra 70ish bucks?? Thanks for the input guys!

 

Good morning. If you will post questions in the appropriate forums we will be able to better help you so I'l move this on over. This is one of the most commonly asked questions on the forum so use the search function here or Google for the answers you seek.

 

If you're talking about the TB spacer then sure, I've heard it works. as for intake. I think it would come down to what you like and what you can afford. Any system would probably be better than the stock air box.

 

Why?

How so?

At what cost?

Telcoman

 

OP, what Telcoman is really getting at:

Stay with the OEM intake box. Almost all aftermarket intakes will cost you power; the others don't offer any gains. You can switch out the OEM baffled tube to a 350Z-tube for a change in tone and more noise at WOT. Bolts right in, no muss no fuss.

Search for a thread where dyno testing was done on numerous common intakes to conclusively show none are better than OEM.

 

The R2C intake utilized part of the OEM cold air system and seals (mostly) the filter from under hood air. But the factory system is pretty good so you won't get big gains. I'd suggest just getting the Z-tube for now and a 5/16" plenum spacer.

 

And I'd add to Scott's advice a quality cleanable dry filter for the OEM intake like an AEM.
