Detailed Description

This Dorman OE FIX oil filter housing is engineered for vehicles where the original plastic adapter can warp, crack, or leak over time. By using an aluminum housing instead of the factory-style plastic design, Dorman 926-434 provides a more durable service part for BMW 330i, BMW 430i, BMW X3, BMW 530i, and Toyota GR Supra models listed in the fitment data. This part cross-references URO 11428596283 for the same application.

Use Dorman 926-434 when servicing an oil filter housing leak, replacing a cracked adapter, or restoring sealing integrity after repeated oil changes. The included seals and gaskets support a proper reseal at the housing-to-engine interface, while the integrated oil cooler and cap help complete the repair with OE-style fitment.

What It Helps Fix

• Oil leaks from a warped or cracked oil filter housing
• Seepage around the housing seals and mounting surface
• Damage caused by overtightening the oil filter cap
• Heat- and chemical-related deterioration of the original plastic housing
• Recurring service issues on BMW and Toyota GR Supra oil filter adapter assemblies

Installation Notes and Tips

Confirm engine code and housing style before ordering, since fitment varies by model and year. Clean the mounting surface thoroughly before installation, replace all sealing points during service, and torque the oil filter cap to specification to avoid repeat damage.
