:usa: I have a 2009 with the 4.0 engine. Was looking for better mpg and have the engine run more efficiently. I added the KKM air cleaner and that increased throttle response and made the Explorer .7 seconds faster 0-60. I then removed the factory muffler and installed a Flowmaster 50 Series Delta muffler. I is a bit louder but I like the new sound, if there is a need for a You Tube video of how it sounds just let me know and I will post the videos on you tube.
I like the results of the air cleaner and muffler.
