Review on Jet Performance 62130 Powr Flo Spacer by Cody Johnson

This is a must have if you have a 5.4 Tritan. This engine has its drawbacks and that throttle body gasket that draws in a lot more air really helps. If you don't have this engine and are still looking for a throttle body gasket, I would recommend installing at least one other airflow modifier with it (exhaust, manifold, custom air intake, etc.). I've noticed a little more boost in the lower power limit and surprisingly I'm getting 0.5-1mpg better depending on how I ride it. It's not much, but it pays off in the end. It also has a little whistle that goes through the 2nd and 3rd, I like the way it sounds and honestly wish it had a little more whistle. Overall super satisfied and super easy installation.
