    A point to consider guys, these Stett boots are not merely bling. Look at the OEM upper boot, it's shaped nicely and smooth on the inside and outside. Now look at the lower boot, it's corrugated to make the bend to connect to the throttle body (TB). The Stett boots are silicone, smooth on both the inside and outside, both the upper and lower boots. What's this mean, as your air is induced into your engine, you want the smoothest, least turbulent air flow, that allows the air to compress itself from the force of induction and then fuel to blend with the denser, more compressed air more efficiently. However, our stock intake boots are corrugated just before the air enters the TB, this introduces some turbulence in the air flow, breaks up any compression of the air that has occurred to that point, turbulence does not permit the air to blend with the fuel most efficiently. Not sure how much, if any, change this would show on a dyno, but you can feel it in the butt dyno when combined with other mods.

    Not a sermon, just a personal observation.

    OMG. You got a response from Stett Performance????!! I emailed them off and on for the better part of two years and never got a response.... WOW.

    Anyhow, I'm running a one piece intake boot from a 3.0 X5. Works flawleslly , and it was only $40.

    Thanks Bruce for chiming in! I'm glad I listened to you and got this! There is a noticeable difference in how my ZHP performs with this intake boot but then I have incorporated so many performance mods but they all add up nicely to what I now enjoy on a daily basis… can't thank you enough! You did an awesome job on your post so I copied it to the intro post for everyone to read

    Yeah, I figured I would just try sending them an email (couldn't hurt) and ask them when they would have a set available. They responded and told me they had a red set available so I snagged it. Blended perfectly with my ZHP I sent them another email thanking them and that I was pleased with their product. They responded again so I posted their email on my GB intro post.

    I did relay pricing as Dane commented and am waiting for their response. Once I get their response I will update my initial post with the information.
