S&B JLT Air B ox Blow Through 2011-14 Mustang GT SUPERCHARGED Supercharger Tuning Required

JLT Blow Through Air Box for 2011-2014 Mustang GT 5.0 with Paxton or Vortech Supercharger.

Kit Includes:

• JLT 4.5 inch Flow Tube (Tube that the filter attaches too, not the compete tube to the supercharger)
• Silicone Reducer
• Roto-molded Heat Shield that ties into the stock fresh air inlet in the grille as well as sealing to the hood
• 4.5x9 inch Red Oil Air Filter 
• Hood Insert for use on 2013-14 models
• Hose clamps

We had good results with our dyno testing with the kit. First we ran the car the way it comes from Paxton with the stock airbox in a blow through MAF set up. Then we swapped out the stock box for the new JLT Air Box and made a couple more runs. The increased air flow resulted in an additional 1.5 PSI of boost and 20-30 RWHP and RWTQ increases throughout the runs. This was all with no additional Tuning although any time you make changes to a supercharged car you should have your tune checked.
