KATANA Port Plates for LT1/LT4 Engines

TooHighPsi's new 'Patent Pending' KATANA Plates have been completely re-designed and are the thinnest port plates available for your GM LT1/LT4 Gen V application. KATANA Plates have been engineered to minimize the amount of vertical height increase of the supercharger or intake manifold allowing for easier installation, with more available hood and cowl clearance for improved bolt access. At only 13.5mm (0.532") thick, our extremely thin KATANA Plates raise the supercharger/manifold vertically only 15.8mm or (0.630"), providing an extra 4mm (0.17") clearance compared to any other plates on the market while also providing an additional 20% weight saving. The KATANA plates utilize an improved port design, resulting in a smoother transition from intake/SC to the cylinder heads and one fuel rail now includes three -8 ORB connections for better fitment on Camaro and CTSV applications. Vehicle Fitment: KATANA Plates are a direct bolt on for stock LT4 supercharger vehicle applications, plus t
