For BMW Engine Under Cover Splash Shield Guard Body Bolts & U-nut Clips 40-80PCS
Product Overview
The engine undercover splash shield is a critical component that protects your BMW’s engine bay from road debris, mud, water, and gravel. Over time, the factory-installed bolts and U-nut clips can corrode, break, or become lost, leading to a loose, rattling splash shield or even complete detachment. This not only compromises engine protection but also increases aerodynamic drag and noise. Replacing worn or missing fasteners is essential to keep the undercarriage secure and your engine operating safely.
This AUXITO fastener kit is engineered to match OEM specifications for a wide range of BMW models. Each hex bolt and U-nut clip is made from high-quality metal that resists rust and corrosion, ensuring a long-lasting hold even in harsh weather conditions. The direct replacement design means you can swap out damaged hardware without any modifications — just remove the old fasteners and install the new ones using basic hand tools. Restore factory-level stability and peace of mind with a kit that’s built to last.
Whether you own a classic E30 or a modern F10, this versatile set covers dozens of BMW chassis across the 1, 3, 5, 6, 7, 8 Series, X3, X5, X6, Z3, Z4, and even MINI. Priced affordably and bundled in a 40–80 piece configuration, it’s the smart choice for DIY enthusiasts and professional mechanics alike. Secure your splash shield, side skirts, bumpers, and other trim with confidence.
