This Moroso windage tray has a louvered design that allows any oil thrown from the rotating assembly to drain back into the sump without splashing back, which in turn reduces windage, increases power, and lowers oil temperature. Designed as a direct replacement for Moroso Oil Pan 710-20385 Old Style (oil pan is stamped with 20385 or not stamped at all)
Increase Engine Performance with a Moroso Windage Tray
Moroso direct-fit windage trays are louvered to reduce windage horsepower loss and to provide quick drainback for oil thrown from the crankshaft at high rpm. Manufactured from 16-gauge steel, these trays are designed to fit Moroso pans and may require trimming to fit other brands.
