Wunderladen Oil Pan Baffle | 17-23+ Civic Type R FK8 & FL5, 23+ Integra Type S DE5

For owners pushing their Honda Civic Type R or Integra Type S hard on track or street, oil starvation under high-cornering load is a real threat. The factory configuration offers no oil pan baffling, leaving the engine vulnerable during aggressive driving. Wunderladen Racing’s Oil Pan Baffle solves that by replacing the factory windage tray with a precision-engineered system that maintains consistent oil pressure and minimizes oil aeration.

Key Features & Benefits

• 100% Bolt-In Installation
  No welding or modification required; installs directly in place of the factory windage tray.

• One-Way Trap Doors (×8)
  These valves permit oil flow toward the pickup but prevent reverse flow, ensuring supply under lateral acceleration.

• Three-Direction Surge Plates
  Strategically placed to counter oil slosh in all directions, conforming tightly to the factory pan.

• Precision Windage Tray Design
  Minimizes oil aeration, keeps oil directed downward, and isolates the crank area from turbulence.

• Tested & Validated Performance
  Backed by data gathered from over 50,000 data points in controlled A/B comparison — significant pressure dips seen in the stock setup were eliminated once installed.

• Crank Clearance Warning & Prep Notes
  After installing the baffle (and before final oil pan installation), it's recommended to rotate the crank by hand to ensure no interference with connecting rods. Clean mating surfaces thoroughly, and use oil-free surfaces for proper RTV seal.

Why It Matters

During hard cornering or braking, oil can slosh away from the pickup, causing the pump to draw air instead of oil. This leads to a sudden drop in pressure, aeration, and loss of the vital oil film that protects bearings and crank surfaces. Within seconds, metal-to-metal contact can occur — generating heat, friction, and potential engine failure.

A properly designed oil pan baffle prevents this by keeping oil around the pickup at all times, maintaining consistent pressure and ensuring reliable lubrication under high-G loads.
