I have a cold air intake and exhaust. The jet v-force plus allowed my car to except Y other mods. Runs much smoother. Does exactly what it says.

Read that works best if used with premium fuel, have ran premium in it the whole time I've owned my jeep. It does actually work as advertised. More power across entire RPM range, has increased my mpg by only 2 though nut still an improvement.
