BMW Engine Oil Filter Housing Bolt Kit 3-Piece (M8 x 28mm / 43mm / 78mm) for N20 / N26 / N51 / N52 / N53 / N54 / N55 / S55 Engines (Replaces 11427540759 / 11427540758 / 11427540763)

Replace your aged oil filter housing bolts with this premium 3-piece bolt kit, manufactured to factory specifications for safe, reliable oil filter housing reinstallation across the entire modern BMW engine lineup. As any BMW technician will tell you, reusing old oil filter housing bolts dramatically increases the risk of bolt breakage during reinstallation — a particularly costly failure scenario where a snapped bolt can require cylinder head removal to extract the broken piece. Professional repair shops universally recommend replacing these bolts with new fasteners every time the oil filter housing is removed for service. This 3-piece kit provides all three correctly-sized M8 bolts (28mm, 43mm, and 78mm lengths) needed to safely reinstall the oil filter housing during gasket replacement, oil cooler service, or related maintenance work — eliminating the breakage risk and protecting your investment in the larger repair.

Why New Bolts Matter:

BMW oil filter housing bolts are torque-to-yield style fasteners that stretch slightly during initial installation. When reused after removal, the bolts can fracture during reinstallation — particularly the longer 78mm bolt which experiences the highest stress concentration. A snapped bolt inside the cylinder head requires either specialized extraction tools (best case) or cylinder head removal for proper extraction (worst case), turning a routine $50-100 gasket replacement into a $1,500-3,000+ repair. Professional repair shops universally replace these bolts during every oil filter housing service. The cost of new bolts is trivial compared to the potential repair cost of a broken bolt.

Benefits:

• Eliminates the bolt breakage risk during oil filter housing service – professional shops universally replace these bolts every time the housing is removed
• Critical insurance against catastrophic repair scenarios – a snapped bolt can turn a routine repair into a complete cylinder head removal job
• Direct OE-spec replacement ensures correct fit and proper torque retention
• Complete 3-bolt kit eliminates the need to source individual bolts in different lengths separately
• Wide engine compatibility makes this versatile for BMW enthusiasts and shops servicing diverse BMW models
• Affordable peace of mind during oil filter housing gasket service – pairs perfectly with oil filter housing gasket replacement
• Pairs naturally with oil filter housing gasket and oil cooler seal kits for complete oil system service

Installation Notes:

• E12 socket required: These bolts use an E12 external Torx socket – verify you have this tool before beginning installation
• Tightening torque: All three bolts use the same 22 Nm (~16 ft-lbs) torque specification
• Single-use bolts: Always replace these bolts with new fasteners each time the oil filter housing is removed – do NOT reuse old bolts
• Allow the engine to fully cool before beginning oil filter housing service to avoid burns from hot engine components
• Document the original bolt positioning before removal – different lengths go in specific positions
• The longest 78mm bolt typically goes in a specific position – consult vehicle service documentation for proper bolt placement
• Clean all mating surfaces thoroughly before reassembly – any debris or old gasket material will compromise the new gasket seal
• Apply a small amount of clean engine oil to the bolt threads before installation – this ensures accurate torque readings and prevents thread galling
• Tighten all three bolts to the specified 22 Nm torque using a calibrated torque wrench – do NOT overtighten which can damage threads or cause bolt breakage
• Follow proper torque sequence per service procedure for your specific engine variant
• Verify proper installation by inspecting for oil leaks after the engine reaches operating temperature
• Professional installation strongly recommended unless you have experience with BMW engine oil system service procedures
• If unsure about compatibility with your specific BMW variant or engine code, contact our team with your year, model, and engine code before ordering
