We also installed and tested a high-flow exhaust system and a cold air intake system, then compared those results against common MPG claims. 

Other fuel-saving methods were analyzed as well, including inflating tires to the maximum recommended pressure and slowing down to improve fuel economy. The goal was simple: find out what really works, what barely helps, and what might just be a waste of money. 

Products Tested: High Flow Exhaust, Cold Air Intake, SUPERCHIPS FLASHPAQ Tuner, Ferox Fuel Additives, Obdiicats, Turbonator, ecoOBD2, nitroOBD2, and the NeoSocket
