Turner Motorsport Alloy Aluminium/Aluminum Skid Plate / Sump Guard Undertray for BMW M3 E90 E92 E93 (E9X) - Engine Splash Shield Belly Pan Replacement, Underbody Protection, Track/Road Bash Plate, Front Lower Cover, S65 V8 Protection

Heavy‑duty underbody protection for BMW M3 E90, E92, E93

Stop cracking fragile plastic belly pans and protect your S65 V8 with a premium alloy sump guard engineered specifically for the E9x platform. This robust undertray replaces the flimsy OE front under shield and gives your M3 serious armour against kerbs, steep driveways, speed humps, potholes and road debris while improving ground clearance and durability.

Built from thick 5052 aluminium and supported by steel braces, this front lower cover is a long‑term solution for daily driving, fast road use and track days. Our team has fitted this on customer cars and the feedback has been excellent for noise reduction, fit and finish, and the peace of mind it delivers over multi‑storey car park ramps and uneven roads.

Why this alloy sump guard is a must‑have

• Replaces the brittle factory engine splash shield with a rigid, impact‑resistant aluminium undertray
• Mounts slightly higher than stock for added ground clearance on lowered cars
• Black wrinkle powder coat keeps a discreet OE look and resists corrosion from road salt and grime
• Fully bolt‑on with stainless fasteners — no drilling, no cutting, easy to revert to stock
• Integrates cleanly with arch liners and retains the factory oil cooler air duct for proper cooling
