Oil Filter Adapter GM LS 90-Degree

The Oil Filter Adapter GM LS 90-Degree by MOROSO is an essential component for LS-platform engine builders and enthusiasts pursuing modern oil system configurations. This adapter solves a common packaging challenge when retrofitting LS engines into older vehicles or custom builds where factory oil filter housing orientation conflicts with headers, intake manifolds, or tight engine bay layouts.

Whether you're building a street machine, restoration project, or performance platform, the 90-degree angle repositions your oil filter to eliminate clearance issues without sacrificing filtration efficiency or flow capacity. Manufactured by MOROSO, a trusted brand in engine accessory innovation, this adapter features precision-engineered porting that maintains full oil pressure and flow rates while redirecting the filter assembly at a right angle to the engine block.

Ideal for custom fabricators, engine swap specialists, and performance enthusiasts, this adapter integrates seamlessly into any LS build facing spatial constraints. Installation is straightforward—simply bolt the adapter to the stock oil filter boss location, ensuring compatibility with GM LS engines (LS1, LS2, LS3, LS6, and LS9 variants) and standard oil filter threads.
