JK Wrangler Supercharger - Sprintex 3.8L V6
How about a Supercharger to enliven that anemic V6 you've got under the hood, my friend...what a difference it makes in towing and passing power!
They ain't cheap...but they really make your Jeep SO much more driveable!!
for more info...we can make you a stellar deal on this kit, (sale prices only through the end of 2012)
