    Extremely good quality intake, just bought mine yesterday. The install took like 45 min and I am very pleased. If you wanna feel stronger pulls especially on 2nd and 3rd then this is the intake for you!!

    • Q: which intake  Scooby snacks18 years ago

      In your last sentence you said intake which one the cobb sf or the AEM CAI. And being that I have an 02 wrx do I need a tune after I add a full invidia exhaust system? I am gonna go with the AEM I think just to save on money. If i do need a tune should I get the cobb AP or just get a protune? Also thank you for the information!!!

        A:  Cobb does not currently have a MAP to support the AEM intake for the 02-07 models unfortunately. And a tune is always recommend after the installation of any intake just to be safe, plus you would see really nice gains with an intake, turboback exhaust and a tune. And deciding between a pro-tune and the off the shelf map is tough choice, but the pro-tune would give you more power as it is going to be specific for your environment and mods. Let us know if you have any other questions. Thanks.

    • Q: AEM CAI or Cobb SF intake with air box  Scooby snacks18 years ago

      I am so unsure now about what intake I should get. I know everybody is ravin about the cobb sf intake and i was sure as of yesterday that I was going to get one myself but today questions come into play. I see all these install videos with the airbox pairs with the ram air duck, I don't have a ram air duck and im trying to save some money, both the oem and the air duck on your website are expensive. Please give me all the input on both intakes, also if the AEM CAI will work with the Cobb AP?
      • 0 of 0 people found the following answer helpful

        A:  The main differences between this intake and the Cobb intake are the filter location and length of piping. They will both have similar hp and torque gains and the final decision will come down to personal preference. The Cobb filter will be more accessible for cleaning and maintenance and the airbox will make it perform like a cold air intake. Cobb currently does not have any off the shelf maps to support this intake.

    • Q: 2002 WRX  dpalmer8 years ago

      With the install of this, would I need a tune?
      • 1 of 1 people found the following answer helpful

        A:  AEM says that this intake does not require any tuning, but you will not get the full potential out of this or any intake without a tune. I recommend tuning with any aftermarket intake to ensure the safety of the engine and for maximum power gains.

    • Q: 2004 WRX wagon  Kernan1149 years ago

      First off, just to make sure, will this fit the wagon. Also is there a way for water to get to this or is it safe to drive through mud/water?
      • 0 of 0 people found the following answer helpful

        A:  I don't show AEM specifying fitment between the wagon and sedan so I imagine it fits both. The filter does sit relatively low in your fender so if you are in deep enough water/mud it could get sucked into the filer. If you are concerned about water/mud then I would suggest using the AEM filter wrap which is what AEM recommends using to keep water and mud from penetrating your filter.
