The Cummins 08-11 EGR Exhaust Manifold is a high-quality, heat-tolerant bended steel product made in the U.S.A. It offers numerous benefits, including increased fuel mileage by .2 to .3 miles per gallon, increased horsepower by 28 to 32, and lower manifold temps by 300 degrees Fahrenheit. The ceramic coating reduces heat and improves air velocity, while the thicker exhaust flanges and center dividers provide greater strength and durability. With tighter tolerances and 50% more surface contact, this product ensures no leaks and improves gasket life. It replaces OEM number 3683789 and is suitable for Cummins 871 ISX engines from 2008 through 2011.
