The factory blow off valve in the SRT-4 not only vents back into the inlet of the compressor housing, but it also acts as a way to limit boost. Remove the factory installed BOV, and install our block off plate to the compressor housing. Install the 4" piece of pipe with the BOV to the lower intercooler pipe just before the hot side of the intercooler. Kit includes pipe, bov, block off plate, and a pair of hose clamps.
