Keystone NI1228104 Engine Splash Shield Under Cover - Front Left Driver Side

The Keystone NI1228104 is an OEM-replacement front engine splash shield designed for the left (driver) side of the 1993–1997 Nissan Altima. Also commonly referred to as an engine under cover or underbody splash guard, this panel mounts beneath the front engine bay to form a protective barrier between the engine compartment and the road surface below.

The engine splash shield plays a critical role in protecting key underhood components. It deflects water, mud, rocks, and road debris that would otherwise be thrown directly at the engine oil pan, transmission, and related hardware during normal driving. Replacing a missing, cracked, or damaged shield helps prevent premature wear, corrosion, and potential mechanical damage to vulnerable underbody components.

Key Features:

• Direct OEM-style replacement for the left / driver-side front engine under cover
• Replaces OEM part number 758991E400
• Parts Link number: NI1228104
• Designed for precise fit with no cutting, drilling, or modification required
• Manufactured to match original equipment shape, mounting points, and material thickness
• Protects the engine bay underside from water, road debris, and contaminants

This splash shield is a straightforward bolt-on replacement that restores proper underbody protection and helps maintain the long-term reliability of the engine and drivetrain.
