However, to get the best performance with a stg.2 tune, a hi-flow panel filter is strongly recommended (not required), thus making the STOCK intake system to be modified. Ask your tuner...and I never said you COULDN'T use the stock airbox, just that an upgrade to the intake could be a good idea.

    Thats also why it offers no performance gains. I was wrong in stating "no" performance gains. It offers very minimal performance gains with a GOOD TUNE.Depends on how good your tuner is.

    I really don't believe you gained 12whp and 15tq off an intake on a stock engine. Show me a dyno chart because i'm calling bullsh*t. Call BS all you want, but you have to remember that every engine, regardless of ANYTHING, is different, and will see different gains with the same mods. Mine just happened to be more significant, evidently.

    A cai will skew the maf readings more than an sri...read above...you can get tuned for it of course but it will still only offer very small performance gains. The stock turbo will run out of efficiency before the intake system does...hence all of the above statements...I feel like I am beating a dead horse... As stated before, not all if them will react the same. There are some Short-ram intakes that skew the MAF off the charts, and are nearly impossible to tune. It all depends on which one you choose, and what your tuner is REALLY worth.

    umm...we're talking about cai's and sri's here. I know that an upgraded panel filter is an option, but that doesn't make it an sri or cai.

    I'm pretty sure i said earlier that some cai's will create less turbulence than some sri's. My debate was that a well designed sri will always have less(possibly minuscule) turbulence than an well designed cai, but less, none the less.

    Yes a good tuner is a must, but what you say you gained just doesn't add up on any engine on any dyno...

    blah blah blah...lets see some dyno charts...

    Personally, I will not put a new intake on my WRX. Yes you get more HP, but that is more top-end. I prefer the low-end torque. Regardless I would rather a CAI than a SRI, no matter of tuning or wrapping can take back the heat you may get with the SRI over the CAI. If I were to get a new intake it would be a CAI.

    Forget the intake.

    I decided it was pointless really.

    I'd rather focus on full TBE and and upipe and engine management.


    I just did the snorkus/resonator/silence delete (too many names for it).
