Bully Dog Big Rig Intake Manifold Kit for 2004-2007 CAT C11/C13 85140

The Bully Dog Big Rig 2004-2007 CAT C11 & C13 Intake manifold features a wide, graduated style that allows your engine to get as much fresh, clean air as it needs.

Another addition to the Big Rig product line is Bully Dog’s Big Rig Intake Manifolds. The air flow into your cylinders is as important as any other factor in big rig engine performance. With optimal flow of cold, dense air from the intake through the manifold into the cylinders, you can pull more power from your engine, and get reliable, efficient performance.
