    And it looks and works just as the 250 would too probably. It's "cheap" parts ya ok cuz ur paying for a name. It's a air filter intake not a tune.

    I look forward to seeing your design of an sri. Maybe we will be able to show others that it's possible.

    It might be possible to completely bypass the MAF sensor with the trifecta ECP enabled tune. Worth looking into...

    Would there be any benifit to doing this?

    Here is a list of what I used:
    Spectre air filter oiled - red to match my car.
    2.5" to 3" silicon coupled - red
    3" 90deg bend
    3" 60deg bend
    3" maf adaptor with 2.75" velocity tube.
    Bracket made out of spare aluminum angle I had laying around.

    This spring when it warms up I will be painting the whole assembly in red heat resistant paint.

    I could not see myself spending 250 plus on an intake, and that is why I decided to fabricate my own version.

    To be honest, any of the aftermarket systems will be of higher quality than the plastic one you put together, so you can't really say that you did the same thing.

    Also, the aftermarket systems are designed and tuned to run on a stock Cruze properly. Now, I haven't done this myself, but have you measured the inner diameter of the factory tube? What is the inner diameter of the tube you're using?

    Any variation there will result in fueling problems. They may not be large enough to throw a code, but to say that it works well would be a tad bit misleading unless you have either tuned of the difference or have verified that the car is running the correct AFR.

    I'm fairly certain that would result in a drop in fuel economy if you could even do it. There's a reason that MAF sensor is there.

    It's more than just an air filter. It's testing that was done by a company to ensure that the intake itself doesn't alter your fuel trims and performs the same as the factory intake with regard to MAF sensor calibration. It's testing that was done to ensure that filtration capabilities are up to par and that you will not break or dirty up your MAF sensor prematurely. It's also support stating that this will not void your warranty, so that if your dealership finds your intake and attempts to void your 5 year, 100,000 mile powertrain warranty, you can cite that K&N or Injen have stated that this is compatible with this vehicle and does not alter the calibration in any way, and does not void the warranty. Good luck explaining how a DIY AutoZone intake does the same.

    Just saying, there's more to it.

    If you look at an Injen intake, not only is it painted with a very nice finish, but it is also tuned correctly. There is a tube inside opposite of the opening for the MAF sensor that straightens the airflow and compensates for any change in pipe area in the MAF section. The elbows are mandrel bent aluminum, and the filter is a very, very good Amsoil dry filter. It would be cost prohibitive to build the same level of quality on your own.

    I bought my Injen intake used with 15k miles on it for $140 shipped.

    ECP = Enhanced Charge Prediction

    To quote Jerry@BNR
    "With ECP the MAF is considered "untrusted" so we ignore the readings it's sending. If you want, we can turn it back on to show airflow but it is not to be considered accurate by any means. "

    I gather that they use other sensors because most people purchasing trifecta tunes are probably running an intake of some sort. So Vince developed other means of calculating airflow.

    This is why i think you could just plop some tubes and a filter on your turbo intake and call it a day. Just completely remove the MAF and use your $50 intake with your ECP tune.

    The aftermarket intakes have bungs welded to accept the stock MAF sensor. This includes ZZP, Injen, and K&N.

    If you're going to buy a tune, it really doesn't matter what intake you use, but if you are going to run stock, it definitely matters.

    From what I can gather, "ECP" does in new PCMs what VE tables did in older PCMs. The problem with calculating airflow and fueling based on volumetric efficiency is that there will be a hit in optimal fuel economy. At least, that has been my tuning experience. Trifecta has yet to prove any fuel economy gains with their standard tune. I'm not holding my breath that they'll release any related numbers on ECP-enabled tunes.
