PLM Vented Engine Splash Guard Plate – 2017–2021 Honda Civic Type R FK8

PLM Vented Engine Splash Guard Plate – 2017–2021 Honda Civic Type R FK8

Improved Cooling, Smarter Airflow, Bolt-On Performance

The PLM Vented Engine Splash Guard Plate for the 2017–2021 Honda Civic Type R FK8 is a simple yet highly effective upgrade designed to improve engine bay airflow and help manage rising oil and engine temperatures under aggressive driving conditions.

As power levels increase and driving demands become more intense, heat management becomes critical. While Honda equipped the FK8 with a functional hood vent, the factory undertray seals off the underside of the engine bay—trapping hot air and limiting overall airflow. This vented splash guard addresses that issue by allowing hot air to escape from below, promoting cooler operating temperatures without the complexity or cost of an external oil cooler setup.

Precision-engineered from CNC-cut aluminum, this splash guard features strategically placed vents to enhance airflow while retaining proper protection for vital engine components. Designed as a direct bolt-on replacement, it installs using factory mounting points and hardware for a clean, OEM-style fit.

Proudly designed and manufactured in the USA, the PLM Vented Engine Splash Guard Plate is an essential upgrade for FK8 owners who want better heat control, improved efficiency, and long-term reliability for both street and track use.
