Welcome!

Most guys get cheapy intakes and put a nice filter on the end. It is less restrictive then the stock air box so it does free up some power and the throttle response is better. I have an Injen CAI. I bought it used for $100 but would probably not pay retail for it, which is like $2xx. It does make the engine sound better also.

I just bought a AEM V2, Will be getting it wensday (SRI) Short Ram Intake. As for you questions It does Improve Gas millage slightly (But your driving could also very that week) So it's hard to tell it adds very little power maybe 1-5 (If you're lucky) Throttle response is better, And a dyno will tell you that your car is running higher power with it. But the real reason we buy them is for the sound it makes. Intake + Vtec = Panty Dropppper

 

intakes dont tend to show gains in hp, any significant hp that is. it just sucks up more air than the stock intake dosnt. this is good for things like at higher rpms. it also makes a louder sound than the stock air box produces. this is all my take on SRI not CAI

 

i bought the AEM short ram intake on amazon for about 130$ id say it was worth the money i could feel a little bit more power and also a more beefy engine sound

 

IMO anyone can get a CAI kit off ebay for as low as 35 usd and it will perform the same as high dollar AEM, K+N, etc... HP and TQ gains are very minimal, as well as mpg, but every little thing working together does count.

 

I kinda want a SRI to improve my MPG but I've heard some people are getting worse MPG with either a CAI or a SRI. My understanding is SRI will give better MPG because your getting warmer air, and CAI give worse MPG, but haven't seen people report consistent results with either :-(

 

SRI may give better mpg results but driving habits and tires will play a bigger part in MPG's. Its hard to get consistent data with MPG because everyone drives different in different parts of the country with various mileage on their cars.

Cheap MPG gains can be grasped by better flowing intake and exhaust. A good high flow air filter(keep in mind its better for a plastic intake tube than aluminum), a good performance muffler. Intricate upgrades requiring more patience and mechanical skill will give mpg gains: a mild ported head, mild ported tb, and underdrive pulley(as we should all know the lighter the weight, the quicker the spool, lesser the drag)... of course then more expensive things like boosting, tuning, and other pro mods will help. Most of us will prefer to keep the luxury of power steering and a/c but those deleted generate more MPG as well. Power to the wheel(s) is gained through things listed as well. Forgive me if I missed something, and please correct me with your knowledge if I'm wrong.

 

good mpg from the factory....

It was always my impresion that our cars were set up at the factory to get the best gas milage possible while still having decent performance...with that being said, increasing horsepower will never give you better gas milage...the more power wanted, the more gas needed. unless you want to do some serious computer programming to milk the last drop of MPG.

The two easiest ways to improve gas milage are to 1) change your driving habits; no fast starts, use cruise control on highway, do speed limit.... 2) change your tires to something with a smaller contact patch....which means that you will have to get rid of your bigger rims and get some taller tires, less tire contact means less rolling resistance....

Just remember that anything you do to modify your car is going to affect the MPG...

sorry if this seems like a rant!

Sorry for thread highjack, and off topic a bit.

I highly agree with driving habits dictate ultimately mpg achieved.

I disagree with the bold underlined statement though. Its all perspective, just because you generate more hp to the wheels does not mean you lessen the mpg possible always. The easier air gets in and out of your engine, the easier you engines crank can spin, the more mpg you can get with economy driving habits, and at the same time you have generated more power to the wheels.

Specifically, the type of modification you do, can lessen mpg, camming, the wrong amount of porting, incorrect back pressure...the perfect equation is needed for best results.

However, Lets not forget the "two way" mods, turbo charging, and supercharging. Several vehicles turbocharged get better mpg with economy driving habits, yet use the gas up when out boosting.

I specifically aim to port and polish always for better mpg, and a quicker throttle response.

 

what do you guys think of these compared to New Honda Air filter.
