AEV Snorkle banger
Just wondering what people are getting on MPG loss/gain....I know there is one account of highway going up and off-road going down. What are other people's experience with this set up? I JUST ordered mine!!!!

well, when I first got mine, my mpg according to the compy said 14 and I was like 
but I have been driving like I always do, and now it registers around 18mpg... But I have 32's with no reflash so I know it is off, but I fill up less often than I used to... I think my milage is around the same, but once aev comes out with the ram air intake, I think it will go up some more.... Most likely your mpg will dip down, then come back up as the compy gets used to cooler air, and more of it...

Also note that there is NO pre-filter on the River Raider and it is pulling colder air and is being forced in too.

im no genius or anything, but a snorkel like river raiders has to have at least the same MPG benefit that a CAI will give, its basically ramming air into your airbox, and cooler air at that.
P.S. I have a K&N Drop in, and noticed 0 gain in my MPG's. But then again, its a Jeep

the ram effect is negligible as it will suck more than you can stuff in 
What is significant is the temperature difference. I drive a lot at night and see a good 2 mpg increase, it makes sense that the temp under the hood is even higher.

i, also with the river raider have seen real world mpg increases. I have the k and n drop in in addition to rr ram air snorkel. It makes perfect sense why mpg would increase....as it does slightly with a cold air intake, i think it does a lil more so with a snorkel forcing air in. especially on the highway
