Hello. I recently sold my 2018 Grand Cherokee Limited 5.7. One of the items I removed before the sale was this Sprint Booster V3. It makes a difference in throttle response. It works on the 6 or 8 cylinder. I had it on my Jeep for approximately 1.5 years. Never any issues or codes, even when brought to the dealer for any service.
My price includes shipping in the lower 48. Pick up is another option. Located in Long Island , NY.
Here is the link from when I bought it from a fellow forum member.


SOLD/NLA: - Sprint Booster V3 SBJE1033s
I took the Sprinter Booster off my 2017 GJC 3.6L as my wife doesn't want it anymore on the vehicle. Has worked great. Sport and Racing modes, 9 options in each. Asking $180 (Brand new is $290). Comes with everything you see .
