Music man So far working on my escape I have found that the biggest gains I've had were to put an intake on it. Not only did my MPG increase but so did the throttle response. This made my 2.3 wake-up and be a fun SUV to drive. Not only is it fuel efficient but its got a little zip, and Im not stopping there. Some important things to keep in mind are that the escape's parts are very expensive for what you get out of them. Weapon R makes an intake for your year, its expensive but its a step in the right direction. If you feel a little daring and are mechanically inclined try looking at the Make your own cold air box for $15 dollars page on this site, You can see where many have made there own boxes and intake set ups. Good luck and happy tuning! :thumb:
