This Air Filter Secret Has Just Been Revealed! Air Filters Actually Work/Give You Any Power Gains?

I had a few sport cars and every time i had the chance to change my air filter, i was opt for the sport one. They are more easy to install, they give you a high boost on your engine and many people say that it will give you a good MPG range… but wait, this is really true? I took four air filters, included dirty & clean OE filters, a low cost aftermarket filter, and an expensive performance filter and put them to the test. To measure differences in horsepower and torque, each filter was put on a Mustang dynamo-meter, with multiple runs. A VBOX was used to measure real world acceleration differences. The idea behind performance air filters is that a less restrictive air filter means the engine doesn’t have to work as hard to bring in air. That means it’s more efficient, and makes more power. It could also mean the engine pulls in more air, and with more air, the engine can inject more fuel to make more power.
