 Federal-Mogul's patented Nüral® brand pistons, with a cooling gallery integrally cast in the piston head, are designed to withstand the high temperatures and mechanical loads in high-performance turbo-charged diesel and direct-injection gasoline engines.
The crown-cooling gallery piston has a curved cooling gallery, giving it a larger surface area that can remove more heat from the critical combustion chamber area and top-ring groove without allowing increased emissions.
In addition, Nüral uses special alloys that are able to withstand heat and provide superior wear resistance. Our superior piston surface-coating process reduces friction and piston wear.
