I have a 99 Explorer with 4x4 auto 4.0l and just wondering if anyone has any suggestions on getting some better mpg. I have been doing all the maintenance with factory replacements so any suggestions on aftermarket would be apreciated.

 

K & N Filter. I dropped one in mine and get an extra 50-80 miles per tank.

 

Also try aftermarket exhaust.

 

50 extra miles per tank? which filter is that? K&N what model???

(going to the auto store tomorrow)

 

don't turn the key, these trucks are not known for high mpg.
