  1. K&N Cold Air Intake with Amsoil Air Filter

    Before installing this K&N cold air intake with Amsoil air filter, I was getting 11-12 mpg while pulling my 8000 lb 30ft travel trailer. After installing this unit, I averaged 14-15 mpg while pulling the same load. I've noticed great mpg gains while under a load, but minimal while running dry.
