Product Description

Hi-Flow Performance Plenum Lid + Twin 71mm OR Monoblade Throttle Body + Large Oliptical intake

The Ultimate Upgrade package for Ford XR8 and GT Boss 260 & 290 Engines 

Yella Terra is proud to announce the Hi Flow Performance Plenum for the 5.4 4V Boss Engine. The new Plenum can be used for supercharged, turbo and naturally aspirated performance engines.

The revised plenum chamber is designed to provide a balanced hi volume air flow to each port runner. The ability to get more air to your Boss engine, means more power & low end torque. Complemented with your choice of either Twin 71mm OR Monoblade Whipple Throttle Body to eliminate airflow restrictions as seen with stock throttle bodies.  

With the ever increasing demand for power this hi flow plenum delivers an increased 95% flow capability ideal for any performance boss engine.

"So which throttle body is right for me?"... In our experience, there's only a marginal difference in performance. That being said, the Monoblade offers slightly higher CFM, where as the Twinblade has more torque down low. At the end of the day it's your personal preference.
