JLT - AIR BOX for VORTECH & PAXTON Supercharged cars (Draw Through)
The JLT Air Box consists of an ABS Heat Shield that ties into the stock fresh air inlet in the grille as well as seals to the hood, a 4.5” Flow tube, Huge 4.5X9” S&B Powerstack Air Filter, Silicone reducer and all clamps.
We did some dyno testing with the kit with good results. 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 through out the runs.
This is with NO TUNING as it’s a blow through set up. We also have a draw through set up with a large 110mm MAF.
WE RECOMMEND YOU HAVE YOUR TUNE CHECKED ANYTIME YOU MAKE A PART CHANGE ON A SUPERCHARGED CAR!
