Intakes - Stock or Aftermarkets?
 
I'm looking first and foremost for MPGs. I'm stuck trying to figure out the best choice for this and I've heard everything from "Keep it stock" to "K&N is the sex" so I think it's about time for a poll.

You missed a number of brands and folks will certainly point out the site's hands on favorite. :D

I have a mopar intake on my 07WK and to be honest, it cost me in the mileage department. More air in means more fuel needed to keep the a/f ration where it needs to be. That's what gives you the slight increase in hp. An intake will change how the engine sounds and performs and if you are like most you will have a hard time keeping your foot out of the throttle and that doesn't add up to an improvement in fuel consumption.

I love my K&N intake kit. Took about an hour and a half, and I'm getting an average increase of 2 mpg. Sounds great as well.

I'd stay away from K&N and any other manufacturer that uses and oiled filter. I've read way too many times that an oiled filter can cause damage to the internals of the motor (probably more long-term). IMO you can't go wrong with a dry filter.

And I agree with Joe... you missed a few of the popular intakes (BWoody).

Don't think BWoody makes anything for us 3.7s

What size engine? You have any other modifications to your engine/exhaust?

K&N is garbage, go with any other company besides them. I noticed a slight increase in mpg's with my drop-in amsoil filter, only $30 or so. I wouldnt go with a CAI (or hot air intake) if you plan on going off road.
