Short Ram vs. Stock Air Intake for best MPG
Been searching for best MPG improvements and some have said that the stock intake will give better MPG compared to most aftermarket, does this seem true?
If so, anyone want to trade my AEM Short Ram for a stock air filer? :P J |
Re: Short Ram vs. Stock Air Intake for best MPG
should be virtually no difference. with a good filter neither one will register any vacuum at WOT. aluminum tube vs plastic tube. same thing more or less.
i did a back to back with an HKS mushroom on a 3" aluminum tube vs a stock tube with a k&n. absolutely near identical 1/4 mile times and vacuum readings |
Re: Short Ram vs. Stock Air Intake for best MPG
i got 3mpg gain with aem sri. the tube doesnt do anything, its the filter. AEM dryflows have a very good balance for filtering/airflow. k&n and similar ones are not as good imo

Re: Short Ram vs. Stock Air Intake for best MPG
Technically it really depends on the temperature entering the intake. Colder air is more dense and therefore uses more fuel because of that increase of oxygen volume.
Hypermilers are crazy about it: http://ecomodder.com/forum/showthrea...mpg-14440.html |
Re: Short Ram vs. Stock Air Intake for best MPG
Wow, ya, thats too intense for me. Just was more looking if anyone had personal experience like "I used to get 28MPG but now I only get 25..."
|
Re: Short Ram vs. Stock Air Intake for best MPG
I might try and get a stock one and see if there is a difference.

never knew air filter would effect mpg.. learning something everything.

Re: Short Ram vs. Stock Air Intake for best MPG
Just get a icebox or ct drop in filter and call it a day... imo

ALL the good filters. aem dry flow, K&N, hks, greddy etc will not be a restriction on an NA 4 cylinder. a dirty paper filter really can effect mpg though, same with melted cats |
Re: Short Ram vs. Stock Air Intake for best MPG
I personally think if you're worried about gas mileage...keep the car stock. Either one isn't gonna make much if any difference. Making sure you're afr is good will save you more gas than the type of intake

for the most part they don't...unless they are restrictive,

Re: Short Ram vs. Stock Air Intake for best MPG
only purpose for an aftermarket intake is to make a car cooler (no pun intended) ;)

Re: Short Ram vs. Stock Air Intake for best MPG
I got a improvement in my f22 accord of about 2-3mpg. My lexus, I am using the stock box with a k&N filter and I cut up a SRI to use with the stock box. I gained .75 average, but the low end response improved alot. I want to wrap it with heat wrap because it gets a lot of heat soak being above the exhaust.
I think the smoothness of a SRI piping can help with things such as throttle response but the heat soak of metal vs plastic has to be considered as well because the results can me marginal like with my Lex. Filter is key!!! You could have the baddest intake but ya ain't got jack if your using a crappy filter!!! |

Re: Short Ram vs. Stock Air Intake for best MPG
lol the differences are so minuscule it doesn't matter, if you're going for an intake it's all sound really, you're not gonna have noticeable gains so for me I just went with the SRI cause it's cheaper

Re: Short Ram vs. Stock Air Intake for best MPG
neither is better for mpg. if you want BETTER mpg, get a header, new cat and exhaust system. if you want even more, low boost it.

The new aem filters are actually made by k&n...........

Re: Short Ram vs. Stock Air Intake for best MPG
I'm averaging 34 mpg recently (summer) in 50/50 driving with 10 mile trips. I have the OEM air box with a K&N filter and custom tube that replaced the air intake resonator. This tube pulls cool air from the fender like the OEM ITR intake system.
For MPG, it seems that you would want to run warmer intake air, but not to the point of preignition. |

:truth: That's my problem since it is my weekend warrior. I may start out easy on it but it is too hard to not enjoy driving |
Re: Short Ram vs. Stock Air Intake for best MPG
pretty simple stuff; more (denser) air = more fuel, as commanded by the ecm through o2 sensor readings. which equates to more power but lesser fuel mileage.
you want better mileage on your stock ls? try advancing ignition timing 2 or 3 degrees. you'll get a bit more power freed up and actually gain mpg. free of charge |
Re: Short Ram vs. Stock Air Intake for best MPG
i got an intake jus for looks aha
