Just installed the K&N intake this weekend. I just filled the tank yesterday so will see if helps mpg. I love the roar that it gives the engine. And it feels a bit more peppier. Could be in my head tho. I know I should have probably waited and got Bwoody of afe. I'm not complaining about the mpg's. I just didn't know if something was wrong with mine. And I didn't know what to expect. I'm coming from a 97 zj that had a straight 6. I love the hemi. Like I said before I get around 13 mpg.

Re: Fuel economy 5.7 hemi

My wife and I took a road trip to see some friends in Chicago and Milwaukee. On the way home from Milwaukee to Detroit (346 miles) my EVIC averaged at 20.1 (i pretty much kept it at 75mph the whole way home)

Around in the city now i am getting about 15-16.

Re: Fuel economy 5.7 hemi

For all Hemi owners who have not done so, it is well worth it to clean your TB and install a CC. Not only is the engine much smoother and more responsive to tip in throttle response, the MDS is totally undetectable except for a slight sound when ti kicks in (this only became noticable after installing the AFE stage II CAI). After installing the CC and cleaning the TB a week ago, I have driven the same route each day, 45 miles each way, and my hwy mpg has gone up by over 2 mpg. At speeds averaging about 63 mph, I am now getting 20.8 mpg for the same trip I formerly got 18.5. This saves about $7 per fillup at todays prices, so after 13 tankfuls, the CC has already paid for itself.

Re: Fuel economy 5.7 hemi

Only get the Billet Technologies catch can, and not some cheapo ebay unit.
The BT CC is $100, and installing this will keep your throttle body nice and clean. Mine was very gummed up after 60k, and it took at least an hour of scrubbing to clean it but what a huge improvement in the way it runs and drives now.
The intake is still caked full of gunk; has anyone removed the intake and cleaned it, and how difficult is this ? I found a Mopar specialty shop that sells 5 angle CNC ported intakes and eagle adapters for early 5.7's and am thinking of going this route too.

Ok so I've gone through a full tank and about a half of another tank after installing the cold air intake. And I'm not really seeing a boost in the mpg's. According to the EVIC it's says about 13.4 no matter if I'm driving city or highway. I drive about 10 miles a day on highway to work. I don't feel like I'm really aggressive with the gas or anything. I usually am going around 70-75 mph on highway(after I got my ticket of course). So does this sound about right to everyone?
Sidenote: is there any place in the forum that has what abbreviations mean?

Re: Fuel economy 5.7 hemi

I was getting between 8.7 to 9.4 MPG pure city driving (no freeway), 11.2 MPG mixed city and freeway, 13.8 MPG pure highway driving @ 70 MPH.

I replaced a few things like the EGR valve, MAP sensor, air filter (stock), cleaned the TB and now I'm getting 10.2 to 11.2 MPG pure city driving (no freeway), 13 MPG mixed city and freeway, 15.3 MPG pure highway driving @ 70 MPH. I did notice much better fuel economy when driving at 60 MPH, it reached 16 MPG and over.

Re: Fuel economy 5.7 hemi

Something is wrong if you are only getting 16 mpg at 60 mph. I get 21.5 mpg with the 5.7 cruising at 60 mph with the Overland model, the heaviest of the WK's and running on Dest. AT's. The only mod I have is the AFE stage II, and the CC. IT has 63k and the original EGR, PCV, etc. and I just keep up with the proper maintenance. You might have a dragging brake ? One way to check is to pull over after a highway run and feel each wheel, and if one is hot, you have a dragging brake.

Re: Fuel economy 5.7 hemi

How do you see it or fix the dragging brake issue?

I had a feel of my tires after a long trip and all the tires were a bit hot with the front ones being a bit hotter.
