Excellent intake manifold! Gained me 11whp & 22tq after a retune with just swapping this product onto my g37. @ae_vhr

This product definitely works to make wheel horse power AFTER your tune.

I bought this intake manifold for my 2017 370Z. Before, the engine sound was muted and not what you expect from a sports car. After installing this intake manifold, there was a noticeable difference in the sound coming from the engine. Now, my 370Z does sound like a sports car. I recommend this intake manifold strictly for the sound improvement.
