    I've seen time and time again that you, more or less, can't run an aftermarket intake without a tune. Is this referring to aftermarket intakes without MAF cutouts or aftermarket intakes as a whole? Haven't really been able to find much clarity on it online anywhere and wanted to know how screwed...
  2. Engine Modifications
    So right now I have nothing really done to my car besides a Cobb cold air intake. Installed it and haven’t seen much of a difference besides just the sound of the intake. I plan on getting an axleback exhaust for now but was wondering if I should get a tune for the intake. I know for the...

    Hi everyone, I'm new here. Recently joined the WRX community by finally purchasing a 2015 WRX STi. I noticed when buying the car it has an aftermarket Cobb intake (not sure on the specific model, I'll have to open up the airbox to look for serial numbers), but all I know is that the air intake...

  8. Personal For Sale & Wanted
    I am selling my Cobb BigSF intake because I had traded my wrx in and have no use for it. I had purchased the stage 1+ package from Cobb about 4 months ago. (Accessport is in a separate post for sale, will sell as a package also). Had it on for about 4,000 miles so it’s in very good shape. Asking...

    Stock intake and tune except AEM Dryflow filter on my 2010 WRX. Seeing 30F+ above ambient (60F) IATs in stop and go traffic, as high as 60F while sitting in a drive thru, and 10F on highway. Having read all the cons of aftermarket and IATs i.e. Cobb w/ Airbox I thought the stocker would be an...

    Im new here so bear with me...So I just installed the Grimmspeed stealth box intake on my 2020 wrx. I thought the E-tune would come within a couple of days but they're backed up. Is it ok to drive without a tune if I stay out of boost? I don't really want to reinstall stock intake if I don't...

    202 WRX Never been on a forum or had a WRX. Raced super bikes and enduro 2stokes my whole life. I understand mods but have no education on turbo cars or the WRX at all. I want an everyday driver with more bite than stock after test driving. Not looking to race, be loud or break the bank...
  13. Engine Modifications
    Hey guys, First off, I'm new to the forum and while I appreciate everything Subie, I'm personally a nissan/VQ enthusiast. A friend likes what I've done to my car, and he's not quite as used to doing performance mods. He's recently jumped on the bandwagon and asked me to help figure out what to...

    I accidentally snapped off the two bolts that were used to hold the cold air intake bracket. See picture below. Does anyone know how to get them replace? Below picture is a reference. I talked to one mechanics and he suggest I can punch those two bolts out. But I'm not sure if it's the...

    2005 WRX w/225k miles (I drive a lot) Stock Ok, in my previous thread I needed to replace the small hose on the oil cooler due to a pin-hole coolant leak.
