Now that the new CERVINIS COBRA R hood is being placed on the 2014 5.0 , I decided to add KOOKS SUPER STREET SHORTY HEADERS to the engine modifications. KOOKS claims a 10 -12 HP gain. Unlike BBK these are not tuned. They are now added to my BOSS 302 INTAKE ,STEEDA COLD AIR INDUCTION, BOSS 302 ALTERNATOR, GT 500 FAN , FORD RACING ALUMINUM RADIATOR , BBK X PIPE , and BORLA ATAK AXLEBACKS. Install slated for NOVEMBER 2013.
