2.100" Bore Shear Plate 4500 hiboost This is not a shelfWilson Manifolds shear plates are designed to maximize performance of engines using tunnel ram style manifolds. They incorporate a 5 degree taper in the bore to improve flow and feature a specifically sized anti reversion groove machined into the bottom of the plate to help turn back reversion pulses. The extended portions of the plate also block reverse flow and help to atomize fuel, reducing puddling in the manifold. This design helps improve signal
