    Hi guys, today I did the deckplate mod.

    When I removed the mass Airflow Sensor, I noticed the tip looks brown/burnt. Is that normal?

    Pictures below + bonus pic of the deckplate.

    Thanks!

    Is it causing any Codes to trip??

    If not most likely it is fine.

    Thats the cleanest MAF ever.
    Is it new??!

    usually there will be a crud buildup on the tip and the shaft down— like this:

    ...then use the maf cleaner to make it look like the one you have above. Check regularly

    There are also “wires” in the MAF sensor, at the bottom of vertical tube that should be cleaned.

    I reset the EFI after re-installing the CAI box by pulling a 20AMP fuse in n out (Did this for 10 seconds at most, not sure if it has to stay out for a while). I have my OBDII scanner somewhere around the home but I can't find it.

    The car is acting weird, I have to turn the ignition key twice since the first time it stalls. After the car starts, If I accelerate or force the car too much it starts to "stall" or "pull back", not sure how to describe it.

    It might be newish, bought the car a little over a year ago.

    Thanks!

    The thing with the dark brown bulb isn't what you need to clean. It's actually the wires pictured in post #7 that sense the amount of air coming into your intake.

    I wonder if you're sucking in un metered Air upstream from the Mass Air Flow Sensor
