Performance Upgrades & Free Modifications Hello, I have a 2007 F-150 4x4 and I was wondering if there are any free modifications that can be done to gain more horsepower and/or more mileage. Also I have seen an air intake adapter from a company called Autero After Market Products that boasts 2-4 miles per gallon and and additional boost in horsepower as well. This piece talks about a retail cost of around $90.00. I am curioius to see if anyone has tried these products, and if they actually work. If anyone has any information that you feel may be beneficial, please let me know.
