An integral part of any turbo upgrade is how fast the air gets into the turbos. Hence, we developed from scratch our 2.5″ custom hand made tubing that gets rid of the stock restrictive intake from the air box to the turbo inlets. We have seen up to 400 rpm quicker spool time as well as 30 rwhp gains thru out the power band. A core stock aluminum intake is required. It comes with all the hardware including silicone couplers, clamps, and fittings.
