Full-Race Response Manifold designed for instant spool, optimized low end and midrange power delivery. Applying Twin-Scroll Divided-Pulse technology with long, robotically welded thick-wall runners, this manifold will offer increased turbine efficiency, allowing the turbo to spool up very early. Runner geometry is adjusted accordingly for the known tendency of RB engines to run slightly lean in cyl #6. It can fit any size T4 frame turbo from GT35R, GT4088R, GT42R and GT45R. *GT45 requires 5" inlet compressor housing, 6" will not fit! A/C compatible ONLY with the R33 and R34 A/C compressor and lines. Will not work with the R32 A/C system. Lifetime Warranty to original purchaser only.
