Description
Oil restrictors are essential for protecting your engine’s bearing surfaces and controlling oil flow to critical components under high-RPM and forced-induction applications. The Moroso Allen Head restrictors are precision-engineered to maintain optimal oil pressure distribution in newer GM V8s, preventing bearing starvation while reducing parasitic drag on the crankshaft. If you’re running boost, high-horsepower builds, or extended track sessions, these restrictors ensure your engine receives exactly the oil it needs—no more, no less.
