I saw an ad for an air intake today saying how it can improve gas milage. I thought with more air flow, the ecu would compensate by adding more fuel causing milage to go down, but horsepower to go up.
16: Q: How much will this intake improve my gas mileage?
A: A lot of companies will claim their intakes will increase your gas mileage by some inflated number but they really donít know. By increasing the amount of air into your engine, your engine will be able to burn gas more efficiently and in turn crank out more horsepower and torque and therefore decreasing gas usage.
do they give you better or worse milage?
