Turner Motorsport Aluminium Skid Plate / Sump Guard & Engine Undertray (Machined/Milled Finish) for BMW 1 2 3 4 Series F20 F21 F22 F23 F30 F31 F32 F33 F36 RWD - Bash Plate Splash Shield with Oil-Change Access - Not for xDrive

Heavy-duty alloy undertray and sump guard for BMW F2x and F3x platforms in a crisp machined finish. Built to protect. Built to last.

Upgrade your front underbody protection with a robust, machined-finish aluminium shield designed for BMW 1 Series, 2 Series, 3 Series and 4 Series in the F2x and F3x family. This premium underbody cover replaces the flimsy factory splash panel that sags or breaks on speed humps, steep driveways, kerbs and road debris, giving your engine, sump and ancillaries the protection they deserve while keeping the bay cleaner and more secure.

Key benefits

• Engineered 8-gauge 5052-grade aluminium centre panel with 1/8 inch reinforcement for serious impact resistance and durability
• Integrated access hatch for quick oil changes - no need to remove the whole panel
• Retains factory fixings in most locations - only two supplied screws differ from OE
• Works with original wheel arch liners and the front support structure for a tidy, precise fit
• Maintains OEM airflow strategy while improving ground clearance compared with the stock plastic panel
• Includes corrosion-resistant stainless fasteners for long-term reliability
• Simple to revert to standard if required
• Made in USA quality
