i went to ram from CAI and my gas mileage dropped to 26mpg...used to be 28mpg.

is this normal? i wasnt expecting that.

 

2 mpg over a tank isn't anything to worry about, unless you do a controlled test you won't be able to tell anything.

 

its just that iv been consistently getting 27.5-29mpg ever since i got the car.

it might be the extra cold weather..

i guess i'll just switch back to CAI. pain..i just took it off so it would be easier to clean the air filter..

 

the whole CAI = better gas mileage is for older carbed cars that ran rich to begin with, now adays with the maf sensor it senses ore air and it being colder so it knows that it needs to add more fuel to compensate for the denser air its recieving thus CAI= less gass mileage

 

i was thinking that too. but once your car is moving or on the freeway that probably doesnt matter.

my guess is that since the piping is so short and the MAF is so close to the filter. air that passes it didnt "stabilize" and gives the sensor bad readings or something.

but with the CAI pipe its got time "straighten up" and pass the MAF consistantly something like that.

im check it thats right 2morro or something. most likely the 40F air outside when i drive..

 

how does it not matter? at all times when the engine is runing there is air going past the maf sensor and ofcourse if its CAI itll be denser air readings thus more fuel being dumped

 

im going to test that out. but i was assuming that on the freeway the air traveling in your engine bay is going through so fast it wouldnt matter. air temp would be the same as the CAI.

 

No. It doesn't matter how long the pipe is for the air to "stabilize", if the MAF was getting false readings you'd have a CEL. The main issue is that the CAI piping is very long causing more throttle response for the air to get from filter to throttle body. Problem solved.
