MAPerformance Torque Plate for Ecoboost Mustang A torque plate is essential during any boring or honing process. When you torque a head down on the block, the pressure from the bolts will cause the cylinder bore to slightly deform. A torque plate takes the place of the head during machining to simulate any distortion that will be caused when the head studs/bolts are tightened. Using a torque plate while boring and/or honing removes any bore irregularities and enables a true cylindrical shape, while allowing the machine operator access to the bores. Features 2" thick billet aluminum Includes spacers to give proper depth of penetration into the block Works with a wide range of bore sizes 100% Made in the USA Applications 2.3l Mustang Ecoboost Focus ST 2.0l Mazda MZR 2.3l Turbo What's in the Box?
