Moroso 23143 Louvered Windage Tray for Small Block Chevy Engine Oil Pan

The Moroso 23143 Louvered Windage Tray is a performance-enhancing engine component designed to improve oil control and horsepower in small block Chevy applications. This windage tray serves as a direct replacement for Moroso part number 20043 and offers a simple bolt-on installation that works with stock oil pans.

Key Features:

• Louvered design actively directs oil into the pickup area while preventing oil starvation during hard acceleration and cornering
• Prevents sump oil from splashing back onto the rotating crankshaft and connecting rod assembly, reducing parasitic drag
• Increases horsepower by allowing the crank and rods to rotate freely without forcing their way through excess oil
• Built-in static slosh baffle keeps oil moving toward the pickup area and prevents oil from running up the rear of the engine at the #4 cylinder rotating assembly
• Steel construction with black zinc finish provides excellent strength and corrosion resistance
• Mounts directly to the front and rear main caps for secure, precise fitment
• Includes notches to accommodate most stroke combinations and works with both standard and high-volume oil pumps

This windage tray is an essential upgrade for performance and racing applications where consistent oil control and maximum power output are critical. By managing oil movement and reducing windage losses, the Moroso 23143 helps protect your engine while unleashing hidden horsepower.
