Description
Why Choose iFJF Oil Filter Housing Cap?
Your BMW's oil filter housing cap is a critical engine component that seals the oil filter assembly and maintains proper oil pressure throughout the lubrication system. Over time, the OEM plastic cap can crack, strip, or develop leaks from repeated heat cycling and removal during routine oil changes. The iFJF Oil Filter Housing Cap provides a precision-engineered, OEM-spec replacement that restores factory sealing performance at a fraction of the dealership price.
This oil filter housing cover is the plastic cap that screws onto the top of the oil filter housing on cars with the M52 and M54 engines. Made from plastic like OEM, it is easy to install—just need a 36mm socket. Each package includes 1 oil filter cap and 1 O-ring seal.

Step-by-Step Installation Guide
- Park the vehicle on a level surface and allow the engine to cool completely (at least 30 minutes) to prevent burns from hot engine components.
- Open the hood and locate the oil filter housing. On M52 and M54 engines, it sits prominently at the top front of the engine for easy access.
- Clean the area around the cap thoroughly to prevent debris from entering the oil filter housing during removal.
- Using a 36mm socket and ratchet, unscrew the old cap by turning counterclockwise. If it feels stuck, apply gentle and steady pressure—do not use excessive force.
- Remove the old O-ring seal from the cap groove. Use a clean, lint-free cloth to wipe the sealing surface on the housing until completely clean.
- Install the new O-ring onto the new cap, ensuring it seats fully and evenly in the groove without twists.
- Apply a thin film of clean engine oil to the O-ring to prevent binding or pinching during installation.
- Hand-thread the new cap into the housing to avoid cross-threading, then tighten to approximately 25 Nm (18 ft-lbs) using your 36mm socket.
- Start the engine, let it idle for 1–2 minutes, and visually inspect the cap area for any signs of oil seepage.
Frequently Asked Questions
How do I know if my oil filter housing cap needs replacement?
Look for visible cracks on the plastic cap, oil residue or wetness around the filter housing area, a stripped 36mm hex socket on top of the cap, or difficulty achieving a proper seal after an oil change. A burning oil smell or small oil spots under your parked BMW are also telltale signs.
Will this fit my 2001 BMW 325i E46?
Absolutely. This cap is a direct fit for all E46 325i models from 2001 to 2005, which use the M54 engine. It installs with the same standard 36mm socket you already use for your factory cap.
Do I need to replace the O-ring every time?
Yes, we strongly recommend replacing the O-ring seal whenever you replace the cap. A flattened, hardened, or nicked O-ring is the single most common cause of oil filter housing leaks. Our kit always includes a fresh O-ring for this exact reason.
Can a cracked oil filter housing cap cause engine damage?
Yes. A cracked or leaking cap can lead to gradual oil loss and reduced oil pressure over time, potentially causing serious and expensive engine damage if left unaddressed. Replacing it promptly is a simple, low-cost safeguard against major repairs.
What tools do I need for installation?
Only a standard 36mm socket and a ratchet. The oil filter housing cap is one of the easiest BMW maintenance items to replace—most owners complete the job in under 10 minutes with basic hand tools.
