Cummins ISC-PX8 Exhaust Manifold

The Cummins ISC-PX8 Exhaust Manifold is a high-quality and heat-tolerant bended steel product that is made in the U.S.A. This exhaust manifold offers numerous benefits, including increased fuel mileage by .2 to .3 miles per gallon and increased horsepower by 28 to 32. The ceramic coating reduces heat and improves air velocity, resulting in lower manifold temperatures of 300 degrees Fahrenheit and lower EGT's of 80 to 100 degrees Fahrenheit. Additionally, this exhaust manifold reduces turbo lag, improves gasket life, and provides greater strength and durability with thicker exhaust flanges and center dividers. With tighter tolerances and press-fit joints, there are no leaks, and the elimination of sharp turns and twists creates smooth airflow to the turbo. This product is a practical and reliable choice, fitting PX8 and ISC engines from 2008 through 2010, and replacing OEM number 4937714.
