The TurboXS High Performance Intake System for the Evolution X is the perfect starting block to build your Street & Race Monster around. The basis is a high flow filter element which will be able to support your air flow needs. We have also machined the inner diameter of the Mass Air Flow housing to the proper size to keep the Mass Air Flow Calibration in within specification. The recirculation port was welded back into intake pipe properly to reduce any turbulence caused by the bypass valve. We typically see a 15 ft. lbs and 10 whp gain on a stock car, the results only get better when used with a Boost Controller or a Tuned Engine Management.
