I was wondering if an AEM type air intake improves or diminishes gas mileage? I know the free flow picks up a couple of HP but does the kill gas mileage or is it just blending air/ fuel better and using things more efficiently.

 

It draws in MORE air, in turn, wasting more gas cause the ecu is programmed to run at a perfect air/fuel mixture of 14:1...

 

Yes, you get more HP and torque by adding the AEM. It can actually improve your MPG ... IF ... and it is a big IF ... you keep your foot out of it. The new sound of increased air being sucked into the intake is addictive and you may have a hard time driving less aggressive.

So ... yes, you can get better MPG, but will probably get less.

 

your better getting a hot air intake system to help improve your fuel economy cold air intake won't improve it what so ever

 

or... possibley better yet, simply go with a inexpensive K&N or TRD drop in replacement air-filter($40-50) , #1. never have to worry about replacing a air-filter ever again, 2. remove your snorkle off your air-intake/throttle body = and slightly increase mpg by roughly 5-10%

 

Define a WARM-AIR INTAKE??I was seriuosly considering a K/N stock replacement and your saying to take off the fac snorkle?Why would you remove that, for sound or improved airflow OR to let the field mice have a nice home?

 

What is refered to as a "Warm Air-intake" , would be completely removing you stock/factory airbox/snorkle , etc. , and running a pipe from your air-intake throttle body(on the right side of the engine- attaches to the engine- its metal) straight up on the top/right side of your engine and having a cone air-filter there(some have done this w/ a BLITZ cone air filter). For 1st Gen xA or xB , your probably looking about , roughly 4-6 more hp out of this set up , not so sure exactly how much more mpg. On a spring/ summer day , I could see a 5% or so mpg increase.

What I was refering to , was simply removing the snorkle, kicking in a K&N or TRD drop in air filter in the stock air box, gain maybe 1-2 hp (little deeper sounding) , but its a 5-10% increase in mpg, depending upon the time of year, also depending upon how long car is in use(short 5-15 minute drives wont benifit as much- due to the AIR INTAKE Temperature, getting into 70+ F , is when its benificial- and this time of the year(winter) , people are driving in under 50 degree temps outside , so its difficult just getting the engine air temp above 60 degrees

 

Is the MAF effected at all by removing the snokle? If this link works,this looked interesting ,he had it for $145 last week NOT$ 500; http://cgi.ebay.com/ebaymotors/aFe-S...4633QQtcZphoto

 

MAF is NOT affected by removing the snorkle.

I checked that link, that is silly - rediculous $$ to spend on something like that.
If you want an open- cone cleanable/reusable air-filter = mainly for more hp , then go with the BLITZ system = I believe its right at about $200
