Get Your Cool On -- Larger LTR For ROUSH Supercharged F-150 and Raptor

High Capacity Low Temp Radiator from ROUSH Performance provides better cooling for ROUSH-supercharged 2011-2014 5.0L F-150 and 6.2L Raptor trucks.


One of the biggest enemies to a vehicle's power is heat.  This is especially an issue for supercharged applications, where a lot of power (and heat) is generated very quickly.  Heat makes air less dense, which means that it has less power-enabling oxygen per unit volume.  Furthermore, modern day vehicles surrender even more power when things get hot -- they are programmed to do this in an effort to protect the engine against over-heating.  The new LTR (Low Temp Radiator) from ROUSH Performance helps to stave off power-robbing heat with an even larger capacity and thickness -- it has over twice the capacity and is over twice as thick as the previous ROUSH LTR.
