Will installing a cold air intake on my 2009 Ford Ranger XLT really improve its fuel efficiency and horsepower?
Yes if you have a little money to play. They help the most at WOT. You will feel a little more pull if you are sensitive enough to feel it. The extra sound let's you know you are mashing the gas too hard so you let off and save gas. Milage is typically 1/4-3/4 mpg better. If money is a factor check over the entire factory intake and clean up casting errors where parts fit together with a razor. Look at the very end where the air enters and open it up if you can. Sometimes plastic grill work can be filed open to let a little more air get to the opening. Some intake tracks have a restrictive sound muffler in them or a big flap blocking the opening. If you see somthing that looks like it's blocking air for no reason then remove it. It's more fun and free to soup up your stock intake. You may have tubes or canisters in the intake track that seem to go nowhere and do nothing. If they are not blocking air flow then leave them in place. They reduce turbulence and even out pulses to increase flow. I mod or replace them on everthing including company cars because even if it only helps 1/4% you had some fun freeing up the flow and you have some feedback sound for when your driving it hard.Will installing a cold air intake on my 2009 Ford Ranger XLT really improve its fuel efficiency and horsepower?
