New TB boots from Ecotrons
Here are 3 boots for Ninja 250r: Old gen carb boot; new gen carb boot; and Ecotrons TB boot.
You can see Ecotrons TB boot is the shortest, which is meant to improve the air flow dynamics at high RPMs.
Also note, Ecotrons TB boots are customized to fit on both ends, TB one one side and engine intake port on the other side, all with grooves and easy to be clamped.
Ecotrons also provides a pair of hard rubber hoses to bridge the TB and the stock air box so you don't have to find your own. But many people replace the stock air box with some performance pod filters, and certainly they don't need these rubber hoses.
