Increase Your HP By Up To 12% with Our Plug n’ Play Flex Fuel Conversion Kit
The 2011-2018 Grand Cherokee SRT8 produces a respectable 470 horsepower with its 6.4L HEMI. That extra HP and torque can come real handy in off-road applications when climbing steep inclines and running jeep obstacle courses but it won’t have any trouble keeping up on the road, either. Converting your Grand Cherokee to E85 will help boost your HP by up to 12% but you will also see savings at the pump which is always welcome in an SUV.
No tuning required!
