POWERWORKS Oil Filter Housing Bolt, Gasket & Cooler Seal Kit for BMW (2006–2021) — Replacement O-ring & Mounting Bolts

POWERWORKS oil filter housing bolt, gasket and cooler seal set is a complete replacement kit engineered to restore leak-free sealing and secure mounting on compatible BMW models.

This kit brings together the oil filter housing gasket, cooler seal and the necessary mounting bolts to replace worn or leaking components on many BMW gasoline engines. It’s designed to match common OEM part numbers (11428637821, 11428637820) and fits an extensive range of 1, 2, 3, 4, 5, 6, 7, X and Z series vehicles from model years roughly 2006–2021. The components are made from durable materials to resist oil exposure and engine heat, helping you avoid drips, oil loss and potential engine damage from a failed housing seal.

Which BMW models will this POWERWORKS kit fit?

The set is compatible with many BMW variants including compact, sedan, coupe and SUV models. It covers specific model-year ranges across series 1, 2, 3, 4, 5, 6, 7, X and Z. Always cross-check the part numbers and your vehicle’s VIN to confirm fit before ordering.

• Fits common models such as 128i, 135i, 320i, 328i, 335i, 428i, 535i, 640i and 740i/740Li.
• Compatible across X1, X3, X4, X5, X6 and Z4 variants listed in the compatibility section.
• Replaces OEM part numbers 11428637821 and 11428637820.

How does this set address oil leaks and maintenance needs?

Replacing the oil filter housing gasket, cooler seal and bolts at the same time removes old, hardened seals and worn fasteners that commonly cause leaks. Using a matched kit simplifies maintenance and reduces the chance of reinstalling failing parts.

• Fresh gasket and cooler O-ring restore a tight seal around the housing and oil cooler interface.
• New bolts ensure correct clamping torque and thread condition for a secure fit.
• Bundled parts save time versus sourcing individual components separately.

What materials and quality features are included in the POWERWORKS kit?

The components are manufactured from materials chosen for oil and heat resistance to withstand typical engine bay conditions. While not OEM, these parts are produced to match the dimensions and function of the referenced factory items for reliable replacement performance.

• Durable gasket material engineered for oil compatibility and temperature stability.
• Sealing O-ring made to resist oil swelling and compression set.
• Corrosion-resistant bolts sized to factory specifications for proper torque retention.

Can I install this kit myself, or should a technician handle it?

Installation is achievable for experienced DIYers with basic mechanical tools and knowledge of engine service procedures, but professional installation is recommended if you lack the right tools or torque specifications. Proper installation prevents leaks and ensures longevity of the repair.

• Requires removal of the oil filter housing and possible routing of nearby components.
• Torque values and clean sealing surfaces are critical—use a torque wrench and clean tools.
• Consider replacing the oil filter and performing an oil change during service.

Who this kit is for: drivers, independent mechanics and repair shops working on BMWs that show signs of oil seepage or who are performing scheduled maintenance on the oil filter housing or cooler. It’s ideal for owners restoring proper sealing without sourcing multiple small parts and for anyone replacing OEM part numbers 11428637821 or 11428637820. Verify vehicle compatibility against the provided model list and your VIN before purchase to ensure a correct fit.
