Review on Spectre 9970 Intake Ford F150 by Blake Pudic

Significant improvement in throttle response and gains of 2mpg city and 3mpg highway when combined with the Jet MAF sensor on the 2010 F150 5.4L V8. It's no joke, your engine sounds like an airplane winding up when you push it, but unless you're driving like @$$Hole, there's very little difference in noise even under acceleration. The installation instructions are ok, better than some of the other things I've installed in the past, only in Chinese, but it skips a few steps. Tip: 1. Assemble the air box first and put the screw heads inside the box to the outside, it will look better when you finish. 2. Before installing the throttle body, install the vacuum port inside out at the 90 degree angle. 3. You will need a 10mm spanner/socket, an 8mm socket or spanner for clamps, a flathead screwdriver and a Phillips screwdriver.
