The AMS EVO VIII/IX F1-I Intake Manifold was designed to outperform every 4G63 manifold available including our own VSR. We referenced many modern design examples and engineering studies to bring you the best intake manifold ever made for the EVO VIII/IX.
Not only does AMS make great products,
but we also believe in making the job easy for the customer.
