Quality, style, performance: designed to mimic the rocker covers of the twin-cam motor, the jagg chrome oil cooler is as beautiful as it is functional.Unlike polished billet “heat sinks” sold as oil coolers, this is a high-performance jagg oil radiator.The billet aluminum end caps and side cover are polished and heavily chromed to create a functional accessory that will provide as many envious glances as years of trouble-free service.
