My truck runs on CNG or gasoline. When running on the CNG it is very temperamental with its need for enough oxygen. Even a slightly dirty air filter will make it run bad at higher RPM's. This COI definitely took care of that issue and I can feel a slight difference in power as well. (its not so noticeable when running on gasoline) It did definitely give it a cool new sound. (especially combined with my aftermarket exhaust)

beautiful piece of work. But way to loud. I have had 2 K&Ns and they neve came close to the noise level. Also it cause some kind of annoying vibration that comes through my dash of my New Truck. 2014 F-150. I am debating whether to keep it or not....
