ALMULOO Engine Splash Shield for Maxima 2016–2023 3.5L — Direct-Fit Plastic Under-Engine Cover

ALMULOO Engine Splash Shield is a direct-fit plastic under-engine cover designed to protect the engine bay of compatible Nissan Maxima and Altima models from road debris and moisture.

This replacement engine splash guard fits 2016–2021 Maxima 3.5L and is also compatible with 2016–2018 Altima 2.5L/3.5L and 2022–2023 Maxima 3.5L trims (Platinum, SR, SV). Molded from resilient, weather-resistant plastic, it restores the factory undercarriage protection after damage or loss of the original shield. The part replaces OEM numbers 75890-9HS0A and NI1228164 and ships as a single splash shield—hardware and instructions are not included.

How does this splash shield protect my vehicle on daily drives?

The shield creates a barrier beneath the engine, reducing the chance that stones, road salt, and twigs will contact sensitive components. By deflecting debris and limiting splash from puddles, it helps keep electrical connections and belts cleaner for longer.

• Molded panels block rocks and branches from striking the engine bay.
• Plastic resistive surface reduces corrosion risk from road salt and water spray.
• Shaped to channel water away from vulnerable undercarriage parts.

Will this part fit my specific Maxima or Altima model?

ALMULOO designed this shield to match the mounting points and contours of 2016–2021 Maxima 3.5L and 2016–2018 Altima 2.5L/3.5L, as well as 2022–2023 Maxima 3.5L (Platinum, SR, SV). Confirm compatibility by comparing your vehicle’s model year and engine size to the listed fitment before ordering.

• Compatible with Maxima 3.5L: 2016–2021 and 2022–2023 (selected trims).
• Compatible with Altima: 2016–2018 (2.5L and 3.5L).
• Replaces OEM 75890-9HS0A and NI1228164; verify against your damaged part.

How difficult is installation and what do I need to install it?

Installation is straightforward for anyone comfortable working under a vehicle: the shield bolts into the factory mounting points. The package contains only the shield itself; you will need the original hardware or replacement clips and fasteners to complete the job.

• Bolts onto existing factory mounting points—no trimming required.
• Hardware and written instructions are not included; extra clips recommended.
• Warming the plastic in sunlight before fitting can ease alignment and flexing.

What material is the shield made from and how durable is it?

The under-engine cover is manufactured from a high-quality, lightweight plastic engineered for automotive use. It’s built to withstand temperature fluctuations and everyday road exposure while keeping weight minimal.

• Lightweight plastic construction for corrosion resistance and longevity.
• Designed for all-weather use—UV and moisture resistant.
• Rigid enough to deflect debris yet flexible enough for secure mounting.

Who is this for: Drivers who need a direct replacement for a missing or damaged factory under-engine shield—especially owners of compatible Nissan Maxima and Altima models seeking a durable, OEM-replacement style guard. Ideal for DIY mechanics, fleet vehicles, and anyone wanting to maintain undercarriage protection without an expensive dealer part.
