## Description

Now available in a sleek, black design, FAST 102mm LSXR and LSXRT Intake Manifolds optimize airflow material and utilize a multi-piece design to provide bolt-on 10-25 horsepower gains. With longer, less restrictive runners and a larger air inlet than stock versions, these FAST 102mm manifolds deliver added horsepower without compromising low-RPM torque. The 102mm low-restriction design yields maximum performance, while a modular, removable runner design allows for easy disassembly and porting. Constructed from an advanced polymer material and featuring an eye-catching black finish, FAST 102 LSXR and LSXRT intakes are lighter than aluminum and run much cooler. The LSXR design is available in three port configurations for LS1/2/6, LS3 and LS7 applications, and is a direct performance replacement to fit stock accessories. Meanwhile the LSXRT is a direct fit for 4.8, 5.3 and 6.0L trucks, as well as engines without clearance concerns. When combined with popular LS upgrades like FAST Big Mouth Throttle Bodies the performance gains are even more pronounced. The manifolds are C.A.R.B.-approved no. D-279-8.
