Baffled Racing Oil Pan for C5 Corvette

EGM-457 Complete Swap Kit $1,235.95

This package couples the factory "bat-wing" style oil pan for the Chevrolet C5 Corvette with Improved Racing's trap door oil pan baffle. Using a factory GM pan allows you to retain the structural rigidity of a cast aluminum pan.

This kit includes the new Improved Racing C5 Corvette trap-door racing oil pan inserts, which are track-proven to prevent oil starvation at up to 1.4 sustained G's while road racing, drifting, drag racing or rock crawling. Save by purchasing the pan and baffle together!

The complete swap kit includes everything you need to swap to this oil pan: the oil pan, Improved Racing baffle, dip stick, dip stick tube, pickup tube, and windage tray.
