    Steam vents on an LS 5.3 single turbo BTR rails and intake. Fits.

    Quality. The steam vent kit looks great. Installing on a single turbo 5.3 with a BTR intake required a little customization of the hose lengths. I also had to add some AN4 90's to get the desired symmetry. Quality product, quality company. Pictures show how tight my space was. I was unfamiliar with SWP, they are now on my shopping list.

    Thanks,

    M

    Steam Vent kit on a 2011 Camaro SS

    Very well made, easy to install. Drilled the two rear holes with a 7/32 bit with a 90 degree drill (would have been much easier with the heads off, but this was an after thought for me) Had to swap from the drivers side vent to the radiator, to the passengers side vent to the radiator due to clearance for the fittings and buy a reducer as the supplied line is smaller than the radiator nipple, but the return line is plenty long enough for this and it works perfect and looks good too.
