How much will a performance air filter improve my gas mileage?
Most vehicles will experience at least a 1-2 mpg improvement in their fuel economy after installing a performance air filter. This results from more efficient fuel burning that gets the most power from every drop of gas. It’s also possible that your driving style will change with the increased horsepower provided by a performance air filter. It is not uncommon for drivers to take advantage of this newfound power by slanting more towards a style of hard driving, which can negate any gas mileage improvements. If you leave your driving style unchanged, though, you should get some relief from soaring gas prices.
