High-flow Billet Throttle Bodies for Chrysler Vehicles
Using state-of-the-art design & manufacturing F&B Performance Engineered Products has produced a
complete line of billet machined throttle bodies for the full range of Mopar-powered rear-wheel-drive vehicles. Our 4.0 Jeep throttle bodys (62 and 68mm) for 2004 to 2008 applications are our latest offering
All F&B designs are dyno and racetrack proven.
Whether you are driving a stock vehicle or a fully modified, supercharged, nitrous spraying, stroked small block,
we have the throttle body to meet your needs.
Our 3D design capability combined with a Computational Fluid Dynamics (CFD) analysis of each throttle body design
gives our products the edge! CFD analysis allows us to confirm and test our designs before we send the files to
our dedicated CNC machine shop. We can iterate the design until we get maximum flow for any given butterfly plate
size. CFD tells us what the throttle body design will flow before we get it on the flow bench!
