Oil Filter Adapter LS M22-1.50 PH10575

The Oil Filter Adapter LS M22-1.50 PH10575 from ALLSTAR PERFORMANCE is an essential component for LS-engine swaps and modern performance builds where OEM oil filter housing orientation or thread patterns don't align with your custom plumbing. This adapter bridges the gap between LS-series powerplants and aftermarket filtration systems, allowing builders to consolidate filter locations, improve engine bay packaging, and maintain precise oil flow without costly modifications to the block itself. Whether you're retrofitting a late-model LS into a classic chassis or optimizing a high-performance street engine, this M22×1.50 threaded adapter eliminates the need for custom fabrication.

Engineered with precision specifications, the M22×1.50 thread pitch ensures a secure, leak-free connection to LS filter heads while accepting the PH10575 spin-on filter standard. The compact 3.55-inch length and lightweight 0.12-pound construction minimize pressure drop and weight penalty, critical factors in high-RPM applications where filter restriction directly impacts oil pressure and engine reliability. Machined from durable materials to withstand sustained boost pressure and thermal cycling, this adapter maintains structural integrity across full-throttle street and strip duty—essential for engines producing 400+ horsepower where oil delivery consistency determines longevity.

Builders installing LS engines in non-factory applications benefit most from this adapter, particularly those working with custom pan designs, remote filter kits, or sandwich-plate configurations requiring standardized thread interface. Installation is straightforward: thread directly onto the LS engine's filter boss with appropriate gasket or o-ring, then attach your chosen spin-on filter or adapter plate downstream. Verify PH10575 filter compatibility and confirm thread-engagement depth before final torque to avoid over-tightening; hand-snug plus one-quarter turn typically secures optimal sealing without galling the aluminum adapter.
