This panel is a thing of beauty. Just what I wanted. A million thanks to my darling wife for this awesome birthday present.
Channels underbody airflow to cool the engine bay faster and stop heat from becoming trapped. A bolt-on fit, no modification needed.

The RX8 engine cooling tray from BEATRUSH gives the front underside a defined aerodynamic role. At speed, air flows along the panel, flushing warmed air from the engine bay. Without it, the underbody acts as a lid, trapping heat beneath the radiator. This 2.0 mm panel is engineered by Laile to solve exactly that. It suits all Series 1 models from 2003 to 2008 and bolts on without any modification. Learn more about the full BEATRUSH catalogue at Laile’s official site.
For rotary enthusiasts running a Series 1, the difference shows when the engine is working hard in traffic or on circuit. Managed underbody airflow means the radiator operates with the car’s geometry working for it.
Temperatures stay more consistent when it matters most. This is the kind of upgrade that reinforces every other cooling improvement already in the build.
The R-MAGIC Super High Flow Water Pump is the natural companion for this RX8 engine cooling tray. It improves coolant circulation through the same system. The GREDDY TRUST Oil Filter rounds out a sensible Series 1 cooling and lubrication refresh.
Keep the genuine Mazda thermostat in place. The Renesis ECU expects Mazda’s intended operating temperature, so the preferred upgrade path runs through better airflow management and hardware like this.

The BEATRUSH engine cooling under panel tray is designed specifically for Series 1 Mazda RX8 models produced from 2003 to 2008. It is not listed as compatible with Series 2 models, so confirm your build year before purchasing.
The tray channels underbody airflow beneath the front of the car in a controlled path around the radiator area, rather than leaving airflow unmanaged under the engine bay. The result is more consistent cooling performance when the engine is working hard, because the radiator is working with the car's geometry rather than against underbody turbulence.
The BEATRUSH panel is function-led, not cosmetic. Its design is specifically aimed at aerodynamic airflow management beneath the engine bay to support the thermal package, making it a meaningful addition to a cooling build rather than a visual upgrade.
The tray integrates naturally alongside radiator, water pump and oil-cooling upgrades, making it a logical early addition to a deliberate cooling build. It works alongside hardware upgrades such as a high-flow water pump and upgraded oil filter to give the overall cooling system a more cohesive foundation.
The tray suits road, sprint and circuit preparation alike. Its underbody airflow management is relevant any time the engine is working hard and sustained cooling consistency matters, so it has a broad use case across different build types.
BEATRUSH is the performance brand of Laile, a Japanese engineering company. The cooling tray reflects the same attention to functional underbody design found across the wider BEATRUSH catalogue of chassis and cooling components.
The recommended approach is to keep the genuine Mazda thermostat in place. The Renesis ECU is calibrated to expect Mazda's intended operating temperature, so the preferred upgrade path runs through airflow management and hardware improvements rather than thermostat changes.
