Full Tilt

C13 Intake Manifold

FT# 47000-1


The Full Tilt C13 Intake Manifold is a direct replacement to any KCB serial number of the C13 and C11 intakes. The inside has been completely redesigned improving not only airflow, but velocity and distribution of clean air into the engine. Our Dyno testing on a stock truck has shown an increase in lower end power response while our on-the-road testing has shown a .1-.2 MPG gain over stock. This manifold will come painted Caterpillar Yellow but can be ordered ceramic coated. As with all our manifolds, all of the design, casting and machining is done in the USA.
