Straight 2.5" coupler with a 1.0" tee port for adding a blow off valve or bypass valve to an FMIC kit. Can also be used to add a blow off valve or bypass valve with 1" inlet to a stock intercooler setup by using this coupler to connect to the throttle body. No need to completely cut the FMIC tubing to add this coupler, simply drill a 1" hole in the tubing and slide this coupler over the tube until it lines the tee port with the drilled hole. Add two 2.88" T-bolt clamps below (or 2.75" clamps if using between the stock intercooler and throttle body) to ensure the couplers don't blow off under boost. Our silicone couplers are constructed of 4 ply material, temperature rated to 392 degrees F, and pressure-rated to 43.5 psi at that 392-degree temperature. Blow Off Valve shown is optional. T-Bolt clamps should be used and are available as an option as well.
