I was just what type/brand of cold air intake system would be recommended for my 05 dodge dakota with a 4.7? I am looking to up my MPG being that the current MPG output is **** poor and "killing me with these current gas prices". Any other MPG increasing ideas are also welcome. I am going to take it in for the TSB concerning the brakes shuddering next week but in the meantime I would apprecaite any advice. The vibration problems concerning the tires "seem" to be solved by changing from the goodyear wranglers to michelin LTX's, but now comes the battle with goodyear to get credit for the POS goodyear wrangler SR-A's that were on previously which I have been getting the runaround from goodyear and dodge with. Any suggestions on the tire situation as well? Thanks.

 

I've used K&N filters on all my cars and bikes.
From the numbers I have been tracking, MPG has gone up about 2mpg.
Aside from that, switching to synthetics all around might pick you up a couple more.

 

With the addition of an Airraid CAI, FLOWMASTER muffler and Mobil 1 in the engine, I get 21.25 mpg highway and 17.8 to 18 city. This is my 4th dak and it's better than any of the other's. My 2002 could get almost 20 mpg highway with the same enhancements..
The BIGGEST factor in fuel mileage is your right foot.

 

i run with the k/n series got a good deal on ebay 222.00 out the door with shipping.also when you get your intake on you might want to relocate your iat sensor. this will give another mile or so better. try installing a 180 thermostat for 8.00 its a good investment.located under lower radiator hose. switching to a good differential lube like royal purple or amsoil will inprove mileage.

 

I use Air Raid. Has a good noise, cost less than K&N and you get the same effects.
