Edelbrock's FAST LS XCR LS3 Intake Manifold with a 112mm inlet (part number 146108B) has been named Best New Product in the Performance Racing category at the 2026 SEMA Show New Products Awards in Las Vegas.

Developed under Edelbrock's FAST (Fuel Air Spark Technology) brand, the LS XCR intake manifold brings race-inspired airflow engineering to LS3 engine applications, delivering substantial horsepower and torque potential in a single-throttle-body package.

Long runners in a compact footprint

The FAST XCR is designed to eliminate the complexity of traditional cross-ram systems. An internal fuel-rail configuration allows for longer, straighter intake runners while keeping the manifold compact. Its 11.5-inch runners are engineered to improve airflow and deliver an ideal cross-sectional area for LS3 engines operating between 2,500 and 7,000 RPM.

The 112mm version accommodates larger throttle bodies while optimizing inlet air velocity and creating a stronger pressure signal for pulsing airflow within the runners. According to Edelbrock, the result is pressure-wave tuning similar in principle to a race-oriented individual-throttle-body system, without the added complexity of multiple throttle bodies and linkage.

Edelbrock says independent testing has demonstrated gains of 30 to 45 horsepower over stock and competing intake manifolds, with torque increases of up to 70 lb-ft compared to popular short-runner designs.

"We're incredibly proud to see the FAST LS XCR recognized in the Performance Racing category," said Cindy Phillips, marketing director of Edelbrock. "This product represents the kind of innovation our team is passionate about, bringing race-inspired engineering and meaningful performance improvements to enthusiasts and builders. Being recognized with a Best New Product award is a tremendous honor."
