Protect your engine under hard driving conditions with this weld-in oil pan baffle designed for M54 and M52TU engines. This upgrade keeps oil where it belongs during aggressive cornering, drifting, and track use—helping maintain consistent oil pressure when it matters most.

Why This Upgrade Matters

Under high lateral G-forces, oil can slosh away from the pickup, causing momentary oil starvation. Even brief pressure loss can lead to accelerated wear or catastrophic engine damage. This oil pan baffle helps control oil movement and ensures a steady supply to the pump during demanding driving conditions.

Key Features:

• Prevents Oil Starvation – Maintains oil around the pickup during hard cornering.
• Integrated Drain-Back Design – Slots allow oil to return quickly to the sump while limiting slosh.
• Track & Drift Proven Concept – Essential protection for performance-driven E46 builds.
• Lightweight Aluminum Construction – Strong, durable, and resistant to heat and oil exposure.
• Weld-In Design – Permanent solution for serious performance use.
