The Cosworth 4G63 Crankscraper is engineered to reduce parasitic drag on the crankshaft caused by oil accumulation that surrounds the crankshaft during rotation. This oil buildup causes additional drag and can reduce power output. Additionally, overall oil control is improved by keeping oil in the sump. Especially useful in high rpm and race applications. Mounts to main bearing girdle.Designed from 2.6 mm (12gauge) steel plate and includes required mounting hardware. Works with OE crankshaft and Cosworth 94mm stroker crankshaft. Crankshaft with longer strokes may require scraper to be modified for clearance. For EVO VII-IX.
