The AMS EVO F1-I Intake Manifold was designed to outperform every 4G63 manifold available including their own VSR. They referenced many modern design examples and engineering studies to bring you the best intake manifold ever made for the EVO VIII/IX. After extensive testing they ended up with a manifold that makes more power than anything else available on the market! EVO's with an aftermarket turbo consistently see 40-60whp (50-70bhp at the crank) over the stock manifold! For many years the AMS VSR has been the standard to which all other manifolds theyre compared. For the F1-I the plan was simple, to take their already power potent VSR and make it even better! Designed, prototyped and tested in house by their team of engineers, the AMS F1-I Intake Manifold outperforms every manifold available! Sheet metal manifolds have significant design restrictions. By casting this manifold it is not only stronger but it allowed us to optimize the power output by giving us the freedom to sculpt the interior geometry for maximum efficiency and airflow. they started with the largest plenum size on the market of 5.24L for the ultimate top-end power. By utilizing a CAD (computer aided design) & CFD (computational fluid dynamics) they staggered the bell horns to allow for maximum inlet size. This allowed us to optimize huge tapered runners and matched cylinder port angles to minimize turbulence and maximize power output. All of this attention to the details in the design process really sets the F1-I manifold apart and results in what matters most... More power than the next guy! The F1-I offers more than just top end power. This manifold gives you an amazingly wide power-band with a huge jump in power whenever you are in boost. This equates to greatly improved lap times on the road course and the confidence to leave any opponent in your dust when on the street! The F1-I goes a step further by offering things the competition does not. From a new oil dip stick, support bracket to 4 drillable nitrous bosses, their engineers thought of everything you will need for installation both now and down the road. They even include detailed instructions and all of the necessary gaskets and hardware in case you want to tackle the job yourself.
