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.
