Description
FAST 146302B LSXR 102mm LS1 & LS2 Intake Manifold
Fits: LS1, LS2 and LS6 engines using cathedral-port cylinder heads, including 243-style heads. Suits applicable Holden SS Commodore VT, VX, VY and VZ LS combinations.
The FAST LSXR 102mm intake manifold is designed for cathedral-port LS engines requiring a larger performance intake system.
Its three-piece modular polymer construction reduces weight and heat transfer compared with an aluminium intake while allowing the manifold to be disassembled for porting. The 102mm inlet suits the FAST Big Mouth 102mm throttle body and can also be used with compatible 90mm and 92mm throttle bodies.
- Three-piece modular manifold construction
- Removable runners for porting
- Integrated nitrous bungs
- Retains compatibility with factory accessories
- Accepts factory LS2 and compatible aftermarket fuel rails

More Information
FAST LSXR Intake Manifold Construction
The FAST 146302B LSXR manifold is manufactured from a polymer material that provides lower weight and reduced heat transfer compared with an aluminium aftermarket intake. Its modular construction allows the individual runners to be removed for porting or inspection.
The manifold uses a 102mm air inlet and includes integrated nitrous bungs. Its bolt-on design allows factory accessories to be retained without the clearance problems associated with some fabricated intake systems.
Throttle Body and Sensor Fitment
Check the throttle-body type, sensor fitment and cable or electronic throttle requirements before ordering. The matching throttle bodies listed above use the appropriate TPS and IAC components from the existing application.
