"After installing the Jet Stage II, I have noticed an increase in both horsepower and torque in the low to mid-range on my 1993 wrangler YJ, 5 speed, 4.0. This is ideal for my use as I am more concerned with its ability on the trails in low range than with high speed highway use. Although it is a daily driver, it rarely sees much interstate miles.
