I had a positive experience with AAM Competition they even went out of their way to help me out with my Z. I had a excellent experience with their customer service and products as well. It just depends what vendors you favor to each their own I say. If you plan on going FI I would definitely consider the AAM Competition VQ37 Performance Intake Manifold would be worth installing and is a quality intake manifold and not worth installing NA in my opinion. If you plan on going NA the Motordyne or Z1 intake manifold would be a better choice in terms of whp and wtq to be cost effective. I wonder what the CJM billet intake manifold will have to offer? I think the CJM billet intake manifold will be worth waiting for!!
