Anytime you're boring a block distortion will occur to the cylinders unless you have a honing/torque plate installed as a brace. Our plate is CNC machined from 2" thick 6061 billet aluminum. The top and bottom sides are face milled to ensure absolute flatness of the plate. Bore size is 90mm. Comes with 1018 steel stud inserts to keep the plate from damaging during the torque down process. Also fits Hyundai 4B11 engines.
