Low End Torque

After installing the intake and resetting battery(which I didn't do during install) I felt an immediate increase in the 1-2 rpm and a HUGE increase in performance when gunning it. I installed an Accel ignition coil a week later and again felt a difference. Thanks for making driving fun again

The performance improvement is great. I had a cat back exhaust system that actually hurt performance due to the intake restriction. The FIPK made a noticeable difference especially with cruise control on. Now it doesn't down-shift automatically on small up-hills. Low end response is much better. I don't run it hard, but when it gets to 3500 rpm it has a little kick now. Not sure about milage improvement, but since it runs smoother and easier, it probably helped. Now I need one for my 95 Bronco 5.8.
