Good then we can trade taillights if I get the '06. If you say no I'll have to steal 'em from you in the parking lot.

Question MAF vs MAP difference

Mass Air Flow sensor right?
What is a MAP
What's the difference.

God Bless Wikapedia

figured out MAP
Manifold Absolute pressure

Some of the information there might help some posting in this thread.
It certainly cleared up any questions I had about CAI on a NA car.

Apparently, correct me if I am wrong, a MAP takes an acurate reading of the air density and velocity regardless of what type of intake you are using then relays that info to the ECU which in turn supplies the correct amount of fuel to the throttle body.

So as far as i can tell, I won't be needing an ECU update unless they make one that addresses timing or other management issues.

I recently purchased a 2002 WRX that had a short INJEN intake installed and also a CEL that indicated a "lean" running condition. I had the stock airbox with a "snorklectomy" put back on and that solved the CEL. I have been told that the stock airbox does a great job of pulling in colder air.

I've had the Injen CAI on mine since it was tuned at 1,000 miles. I had them test it with only the intake at first and some slight tuning. 10 whp, no joke. I can tell you that I've run with some pretty quick Subarus and Evos at the track and they usually comment at how quick my car is compared to theirs. (with very similar mods and stock intake)

I can't tell you how good the car feels, especially at night with cold air hitting that intake.

I even had a rep call me about driving the car in snow and me worrying about it hitting the intake....no problems at all....and Injen was very helpful.

Injen does their research and the even the sound it makes at full throttle is worth every penny.

You can get the same effect with a drop-in filter and ditching the resonator for a velocity stack.Increases the airbox inlet to 3".Plus the Injen metal intake will heatsoak regardless of where the filters at.

I have my spt short ram didnt notice hp increase but it kept me from buying a BOV. got the woosh and sounds great with the spt exhaust. Alot of people buy CAI for more air flow as well as cooler air. side from the cooler air part i dont believe that it needs to draw more air. seeing as that a turbo is basically an air compressor (correct me if i am wrong) there is no need to draw in more air. cooler air is always good though

"Drawing more air" is most certainly beneficial when attempting to increase max power output of any given engine.

yes i agreee but will you really draw more air with a turbo behind it. the turbo charger acts as a air compressor for the engine i domnt think it would see a volume difference but a temp difference on the MAF sure. for naturally aspirated engines i can see the advantage because of all of the crazy turns and loops the stock intakes have but for a turbo engine with basically a stock short ram how much more air would you draw realistically?

I know there are a thousand things out there about this... but I just wanted some direct feedback - I just got an Injen CAI and noticed a better throttle response, awesome sound, and a small accel boost.

But will it jack up my car vs. the stock intake? I am nervous that I will get a bunch of water in it or something... Is it worth just getting the K&N filter for the stock intake?

(I have a 2002 WRX)

^^ Did you read nothing earlier?? ^^

Sell it unless you plan to pay for a tune in the near future. Stock airbox= good to 400HP.

If you like sound...remove snorkus.
