Stamford I completely agree with you, if you follow through and make the upgrade a package then there will be an improvement gained . JMHO I worked in a Ford dealership , I was the night time shop foreman and over the years saw so many people fall for the ads put out by the aftermarket promising huge HP gains or ridiculous fuel mileage increases by simply bolting on their part. When I talked to customers who had problems with their cars created by those parts I had to explain to them that if there was HP or gas mileage to be gained by simply bolting on an air filter that the manufacturers would have installed them at the factory . Today's cars are amazing compared with cars years ago, they last 2 to 3 times longer mileage wise and get incredibly better performance along with increased mileage . Car manufacturers fight for every HP and MPG they get along with durability so if something is simple to do to increase any of those things I believe they were looked at very closely .
