The 2016+ 8thgen Intake Manifold directly fits the 2009-2015 7thgen Maxima. It will also fit other gens (4thgen, 5thgen, 6thgen) that have done the Gen2 VQ35DE (aka HR) engine swap. These can also be used to swap your 2007+ Altima Manifold to a Maxima one (direct fit as well).
You can find and buy these manifolds on eBay for around $150 or less.
Please Note: As of now, there hasn’t been any testing to prove additional gains in comparison to the 2009-2015 7thgen Maxima manifold. We will provide an update as we learn more.
