Replace your air filter with a k@n air filter. They are a lifetime air filter that you clean.
They filter out smaller dirt particles and flow air better
(Do not use in diesel engines ) then bump your tire air pressure up to around 35 psi on most cars
And watch your gas mileage increase by 2 to 3 miles per gallon
