2004-2008 F-150 ROUSH/FOOSE SUPERCHARGED 5.4 500HP UPGRADE KIT

2004-2008 F-150 ROUSH/FOOSE SUPERCHARGED 5.4 500HP UPGRADE KIT

Upgrade your 2004-2008 F150 Roush Supercharged or Foose Edition F-150 with this JDM Engineering 500HP upgrade kit! With 450HP out of the box the Roush and Foose trucks are no slouch. We at JDM like to take things one step further making an already great product even better. Our upgrade kit includes a 2.80" supercharger pulley that adds 4-5psi over stock bringing the total boost level to about 10psi compared to the stock 5-6psi. We include a shorter belt to go along with the smaller supercharger pulley eliminating the chance of belt slip as well as a colder set of spark plugs to help keep things running smooth. 

To tie everything together we also include an SCT X4 flash tuner pre-loaded with our JDM Custom tune specific for your truck, our 500HP upgrade and the intended use of the truck. 

This 500hp Upgrade kit not only increases power but will also drastically improve automatic transmission shifting characteristics and increase throttle response removing any “lag” when attempting to accelerate. 

2004-2008 F-150 JDM 500HP Upgrade Kit Includes:

• SCT X4 Tuner with JDM Custom Tune
• Gates K080594 Belt
• 2.80 Metco Pulley
• Spark Plugs ( HT0 used with black boots 12MM 3V with brown boots) 

Removal of the stock supercharger pulley and installation of the 2.80" pulley requires the use of a pulley removal and install tool. See here for purchase of this tool: VMP/ ROUSH PULLEY PULLER TOOL

*This kit is not compatible with non-intercooled Roush Supercharger kits! 

**JDM Vacuum line rerouting Instructions will be emailed to you by one of our representatives after purchase. This must be done when adding more boost.
