FAST’s LS XCR Intake Wins SEMA 2026 Racing Award: An LS3 Build Checklist
SEMA named the FAST LS XCR LS3 Intake Manifold 112 MM the Performance–Racing Product winner in its 2026 New Product Awards. Edelbrock identifies the winning 112 mm-inlet version as part number 146108B. For an LS3 builder, the useful question is how the manifold fits the complete engine and vehicle package, not what the trophy might imply about any particular car's power.
What the announcement actually says
According to SEMA’s winners list, the FAST manifold took the racing category. In Edelbrock’s announcement, the company describes a single-throttle-body cross-ram layout, internal fuel-rail arrangement, aluminum construction, and 11.5-inch runners. Those are manufacturer-described design features. Published test gains in the release are not a promise for a different engine, tune, or installation.
Confirm the engine and installation envelope
Start with the engine actually in the car: cylinder-head and intake-port configuration, fuel-injection layout, and the exact manifold part number. “LS3” in a product name is not a substitute for a manufacturer application check, especially on swaps or engines assembled from mixed LS components. Verify the mating parts and required hardware against current installation instructions before placing an order.
Then measure the vehicle around the manifold. The throttle opening, inlet duct, hood, firewall, accessory drive, and nearby plumbing all affect whether a particular intake package can be installed cleanly. A cross-ram design also changes the routing question for fuel lines, vacuum, PCV, and breather connections. Edelbrock says its package includes rails, mounting hardware, and O-rings; confirm the exact kit contents and the additional fittings your build needs.
Plan the calibration as part of the hardware choice
An intake change can alter airflow behavior and the location or sizing of supporting components. Discuss the throttle body, injectors, fuel delivery, sensor connections, and ECU calibration with the person who will tune the car. For a street-driven vehicle, also check applicable emissions requirements before committing to the combination. A dyno or road-tune plan should be based on the finished build, not a gain quoted from another test engine.
A practical next step
Bring the engine specification, cylinder-head details, vehicle or swap information, current throttle body and fuel system, and intended use to a parts specialist or performance shop. SMG Speed Shop can help source a compatible intake package and supporting parts; North Texas High Performance can help assess installation and tuning needs for a local build. Confirm current product availability, application, and legal requirements before purchasing.
