Keystone MI1248133 Front Fender Liner Left Driver Side with Insulation Foam Vacuum Form

The Keystone MI1248133 is a direct-fit, OEM-replacement front fender liner for the left (driver) side of the Mitsubishi Outlander (2014–2020). Engineered as a precision replacement for the original front wheelhouse splash shield, this liner is constructed using a vacuum-form process and includes insulation foam — matching the factory design and material specification of the original part.

Fender liners protect critical underhood and wheel well components by shielding them from road debris, water, mud, and road salt. Replacing a damaged or missing liner helps prevent corrosion and premature wear on nearby components such as wiring, brake lines, and suspension hardware.

Key Features:

• OEM replacement design — matches original factory fit and function
• Left (driver) side front fender liner / inner splash shield
• Vacuum-form construction for accurate contour and rigidity
