MMR Performance BMW Billet Aluminium Oil Filter Housing Cap/Cover – CNC Alloy Metal Lid, Direct Replacement/Upgrade for N20 N52 N54 N55 S55 (Canister/Cartridge Cap) Fits 1M, 335i, 435i, M2, M3, M4 – MMR-OFC01

MMR CNC-Machined Alloy Oil Filter Cap for BMW N20 N52 N54 N55 S55

Stop dealing with cracked plastic lids and messy engine bays. This MMR Performance alloy oil filter cap is a direct swap for the fragile factory plastic top, delivering long-term reliability, a premium look and a reassuringly precise feel every time you service your car.

Crafted from solid aluminium and finished in a polished anodised dark anthracite, the cap resists heat and ageing far better than the OE piece. The threads engage smoothly, the seal seats perfectly and the finish looks at home in any high-performance BMW engine bay.

We run this upgrade on our own cars and customer builds and it has been absolutely faultless. Fit and finish are superb, and the confidence it gives during routine oil changes is exactly what you want from a quality part.

Why this upgraded cap is a smart choice

• Replaces the weak plastic cartridge lid that is prone to cracking and weeping
• Aluminium construction for strength, temperature stability and longevity
• Satin dark anthracite anodised finish for a clean OEM-plus appearance
• Direct swap. Uses the standard filter element and O-ring
• Ideal preventative maintenance during an oil service
