No check engine lights are on and it runs like a champ. Any suggestions or ideas? Thank you. OOPs....It has a 5.4 Tritan V8

In all honesty, I simply added a K&N filter (filter only - not the kit) and noticed a 1 - 2 mpg improvement. The engine is a little louder - you can acutually hear the engine sucking in the air.
After awhile, I installed a full K&N air intake system. Felt immediate performace gain, and a great engine growl during hard acceleration. Gas mileage dropped - cuase it's alot more fun to drive with the added power.
