Installed in 2018 JK. I didn't notice any significant increase in fuel consumption. Maybe 2mpg. Paired with a Dynoflo exhaust. Noticed about 3 more mpg. First I mounted the air intake. It sounded a little meaner. Next comes Dinoflo. Looks like a Camaro. Very happy with the pair. Most important now is a huge increase in HP.
