k&n air filter?

[Scott Mikutel]

will this improve gas mileage at all?

 

[Aaron Yarbough]

I bought one for performance more so than increased gas mileage......

 

[Johnny O]

I put one in the Ranger I had before, same 4.0 SOHC engine, and I didn't think it made a difference in anything.

 

[Les]

Probably not...

Anytime you open the airway, it will help. The gas milage is up to you and your foot._Ron

Scott - I actually did my intake first and gained 2 mpg's. I think that and now putting on the y-pipe and high flow cat have been the biggest increases in mpg's of all the mods I have done.
