   The FAST LSXRT 102mm Intake # 146105B (full polymer manifold with runners) is available thru Marken Performance.  This LSXRT High HP version gives LS3 engines with rectangle ports more plenum volume for all-out racing.  The raised 102mm throttle body location optimizes the larger, less restrictive high HP runner design, creating 30+ more HP over the FAST® LS3 Street Manifold at high RPM.  There is ability for nitrous ports and porting.
