Review on Spectre Performance Air Intake Kit SPE-9920: Enhance Horsepower & Torque, Perfect Fit for 97-04 FORD/LINCOLN (Expedition, F150, Navigator) by John Warren

First of all this is a great product that we have seen. The 2 mpg increase in fuel economy went from 11 to 13 in the city and 16.5 to 18.9 on the highway. Second, you need to allow about 4 hours to install and read the instructions, the mass airflow sensor needs to be in a vertical position (laughs). Love is of great importance in strength. Oh, plan to lick with a high-flow muffler, already have high-flow cats, and then add a super chip.
