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

This product was purchased with all the parts needed plus some extra nuts (some extra nuts). It took me a little over 1 hour to complete the installation. Throttle is more responsive and makes a deep rumble when you give it a lot of throttle. But I think the HP gain is few. I would give it 5 stars but there was a scratch on one of the tubes like it had fallen on concrete but for the price I'm not complaining. Works just as well as the K&N sets I've had before. I definitely recommend this set.
