KATANA Port Injection Plates for LTx Engines

$719.95
Description

TooHighPsi’s new “Patent Pending” KATANA Plates have been fully redesigned to be the thinnest port plates available for GM LT1/LT4 Gen V applications. They were engineered to minimize vertical height gain on the supercharger or intake manifold, making installation easier and providing more hood and cowl clearance for improved bolt access.

At just 13.5 mm (0.532") thick, KATANA Plates raise the supercharger or manifold only 15.8 mm (0.630"), offering an extra 4 mm (0.17") of clearance compared to any other plates on the market, along with a 20% weight reduction. The updated port design provides a smoother transition from the intake or supercharger to the cylinder heads, and one fuel rail now features three -8 ORB connections for improved fitment on Camaro and CTS-V applications.

These parts are sold for ground-vehicle use in a controlled environment.

Proudly Engineered and Manufactured in the USA!
