Are you ready to upgrade your Brenspeed 475C package to the Brenspeed CJ519 to take your Mustang to the next level?


The Brenspeed CJ519 package is designed for 2011 to 2014 manual and automatic transmission mustangs. Our CJ519 package has extensive development on the street and at the track and provides a drastic improvement in power over a factory stock 5.0L Mustang and improvement over the 475C.

Upgrading to the Brenspeed CJ519 includes:
  • Ford Performance Cobra Jet Throttle Body. Made from CNC machined aluminum this twin 65mm throttle body has a tapered inlet for consistent high flow.
  • Cobra Jet spec 1 7/8" stainless steel long tube headers. Our CJ519 headers are the same spec as found on the Cobra Jet and built in the same facility as Cobra Jet headers. The major difference is Cobra Jet Mustangs have a 3.5" dump at the header collector. This is not feasible for a street car. Our CJ519 spec headers collect at 3" and are fitted to a catalytic or off road H or X pipe.
  • Hybrid Brenspeed CJ Engine Calibration. Our CJ519 package includes a Brenspeed CJ inspired engine calibration. Many aspects of the CJ will be found in our drag strip only calibration. Our street calibration is tamed down for street use. The package includes both the street and drag strip ready calibrations.
  • 170 degree thermostat for high performance engines, providing high flow to your radiator by mid-180 temps while still providing good all season performance.
  • Also included is a Custom Brenspeed CJ519 Graphics Package available in 4 different finishes.  Gloss Black, Matte Black, Silver, and White.  Exclusive to CJ519 owners only! 


There have been several variations of the Cobra Jet since 2008. Most every example was supercharged but in 2013 Ford released the Naturally Aspirated Cobra Jet Mustang. The Naturally Aspirated Cobra Jet inspired us to develop a package using Cobra Jet spec parts for that individual who was looking for over 500 HP Naturally Aspirated horsepower and loved the Cobra Jet History. The goal was a fast naturally aspirated car that retains as much Cobra Jet heritage as possible yet remains a street car.


2013-14 GT / Boss

Please select from the drop down menu above:

Keep Your Air Filter Dry
Constructed from a thick foam rubber, this Roush Insert Plug installs into the underside hood insulator to block rain water from entering your aftermarket cold air intake or open element air filter.

Heat Extractor Compatible
The Roush insert plug is designed to only block off the lower portion of the vent opening so it still allows underhood engine heat to escape through the factory hood extractors.

Direct Fit
This Roush Performance Hood Vent Insert Plug is specifically designed to fit 2013-2014 GT or BOSS Mustangs with the stock factory heat extractor hood installed.
