Review on 🚀 Spectre Performance Air Intake Kit for 1999-2004 FORD (Excursion, F250, F350, F450, F550) - High-Performance Solution to Enhance Horsepower and Torque - SPE-9921 by Amy Cook

I had to make a few minor changes to make it fit. Unfortunately I don't see any additional performance. Only the gas consumption is worse (didn't think it was possible with v10). And the deeper sound that some other people have mentioned isn't really there either. Kind of a waste I think. I leave it on because it's too much work to change it back. At least I won't have to pay for air filters in the future (just cleaner and oil).
