Which intake gives you the best overall improvment in horsepower, torque, and MPG. I will be having some extra cash here in a little while and I'm gonna buy one.

 

None.
I honestly beleive you can't improve HP and torque and expect an increase in mpg too. If you beleive that, then go buy a Tornado and a throttle body spacer while your at it.

 

Three things you can have with engines: fast, cheap, and reliable. Pick any TWO.

 

Silver,
You read my mind. Ya gotta choose one.

 

Well then what would you recommend that I do to improve airflow?

 

Haven't some people had better throttle response, more powerAND better gas milage with the 14x3 air cleaner?

 

Check out my engine threads. I also have a 318 and I went with a 50mm Fastman TB and I cut the runners down on my intake. I get bitchmileage towing my trailer (18' dovetail tandem axle)

 

Granted I've only had my Ram for about 2 1/2 or 3 weeks now and it already had the K&N intake installed on it so I don't really know what it was like before, I am getting between 16-17 mpg. I try and keep my foot out of it and it seemed to go up since I changed the oil with full synthetic. I don't know if it's the best, but it seems to do a good job.
