    Pieces of overpriced aluminum scrap which have no function. Very similar to a tb spacer.

    Is that the fact sheet or the abridged version?

    I believe they are supposed to disperse the air more evenly instead of the air hitting the flat bottom of the intake.

    That particular pair was designed to be used with the EGR equipped M1 2bbl. You can make them work with the non EGR as well, but takes more work.

    I googled the name and product and found this old archived message on this other board. It talks about size in more detail.

    Your problem isn't the problem. Your reaction is the problem.

    Might be easier to sell if you would separate them.

    I have to agree with this guy. I'd probably buy one for $50 just to see if it works but I have no desire to buy two and attempt to sell one.

    Was hoping Danno would chime in. Glad he did. These not only help direct the airflow reducing turbulance in the plenum, but they also help fill the plenum area increasing velocity, and in turn, vacuum signal. Also more or less increasing length of runners. Jeff did a lot of testing with these, which is why there were three sizes available. As they weren't a one size fits all mod. Large for light bolt ons, medium for heavy NA, and small for boosted applications. He had documented dyno numbers.
