    Can you cut the coupler at an angle to correct it?

    Can you rotate the maf 180 degrees so the connector is facing the engine?

    I tried, but my stock maf connector isnt long enough. Do you know where i might be able to buy an extension?

    I would make this more concise and put it up on your website in the description for the systems. Pretty much answers any and all questions I had when I clicked into this thread for the first time (ever) 5 minutes ago.

    Nice to see actual engineering work being performed here. Seems nowadays its more of how good are you at marketing, vs how good you are at designing functional components. Will definitely be ordering a PMAS intake when the time comes:thumbsup:

    Thank you! I try to put up good information but sometimes I feel like i get too technical. I'm glad someone else notices that the cold air market sometimes turns into who is better at marketing instead of making parts that work and letting the parts speak for themselves.

    I kick myself for not getting into intake systems sooner. All we have ever done here is airflow R&D. If we couldn't design a kit that outperformed everyone else I would be embarrassed.

    There are many among us that appreciate exactly that kind of info. This is a strength and differentiator from others in the market, capitalize on it :cheers:

    Will do!

    Side note, we will soon have tunes from Dennis Gomes (whipple/Tasca) and Jimmy LaRocca (The MAN) available for our kits.

    Potentially stupid question here--are the filters pre-oiled, or do I need to oil before use? Seems like mine has a little bit of oily residue on the black plastic pieces of the filter assembly, so I thought I'd ask.

    Yes, they are pre-oiled. No need to oil the filter.

    Just place a order! Being able to use my OEM MAF sensor like the Jlt was the deal breaker!

    Let see how it compare to my Jlt. Hope it work and bring me closer to 10.90's .

    Hope it will be home soon!

    Awesome! Thanks for the order. You should definatly see a gain over your old kit

    Any word on availability/pricing on a PMAS intake/tune combo?

    Tune required kit is $299 and Lund has the transfer function info to make a tune for it. This data is also included in the kit so you can use any tuner.

    I completely understand how the control system works, but what are the gains without the tune? If you're basically tricking the PCM into thinking it's getting a similar to stock airflow, it won't adjust the A/F to compensate, so won't you be running lean? Perhaps I'm not understanding afterall.

    BTW, I really appreciate you being so technical and showing that you've engineered this product!

    You aren't tricking the PCM. You are getting similar airflow to stock. You are correcting the maf sensor so it AGAIN has the correct frequency output for that same airflow input.. here is an example of a maf table:
    Stock:
    1
    HZ actual FLOW
    1 10
    2 60
    3 200
    4 1000

    The same maf sensor installed into a tube with twice the area as stock
    2
    HZ actual FLOW
    .6 10
    1.7 60
    2.4 200
    3.3 1000

    PMAS maf installed in PMAS tube with corrected maf sensor
    3
    HZ actual FLOW
    1 10
    2 60
    3 200
    4 1000

    There is room in this factory maf table for a lot more power than the stock car makes. This is why the intake can be installed and the stock computer will know what to do with the extra air. Nothing needs to be "tuned" for the extra air the intake will flow. The data is already in the computer.

    Cars need to be tuned with some intakes because you need to enter the skewed data (shown in my second table) Because with an uncorrected maf, you will have a new lower HZ reading coming out of a maf at the same airflow it would have stock. You put your stock maf in a tube twice the size, it will take twice the mass of air passing across the maf to get the original reading.

    The gains have zero to do with air fuel mixture or engine tuning. They are simply from less pressure drop in the intake. (aka restriction) If you double the pressure into an engine, you double the power..ish lol. Remember we don't live at 0PSI we live at 14.5PSIA. If your intake has 28" pressure drop (-1psi) at 400HP your engine will only actually see 13.5PSIA. if you install a free flowing intake that has 0" pressure drop, your engine will now see 14.5PSIA. Now it's not soo hard to see how you can gain 20HP from adding 1PSI of boost. These numbers aren't actual but they are so you get the idea.

    I actually did the math from pressure drop at the outlet of the stock TB and our intake vs the stock intake for a sanity check. It worked out to an intake manifold pressure difference of 1.047. Guess what 430FWHP * 1.047 is? 450HP. A gain of 20 :) The math never lies, and flow data never lies. It's always worked this way. It is this reason that FORD knows almost exactly how much power an engine will make before they even build it.

    For example, you can use this chart for 11-14 kits and know pretty much how much horsepower each system will make. Most of those kits are almost the same for 2015-16. 11-14 cold air compare.jpg
